Love the wife's Q5 - Only two issues I have with it after 15K miles
1) Navigation - maps will never be up to date and finding Points of Interest is horrible (but they CAN get you to the nearest Audi dealer easily!)

2) Not quite enough Oomph for me...

One of the local dealers is a Stasis dealer and came close to that, but wanted to do some research since I come from a tuning background and then read stories like this:

So the holiday sales by the major players interested me...
Looked at APR, AWE, etc... on forums:
http://www.audizine.com/forum/showthread.php/85612-APR-vs-GIAC-vs-REVO-software-comparison-with-datalogs-and-dyno-charts
but decided on Revo since there's a KNOWLEDGEABLE installer in my area...

Have only driven it from the installer to the house because we have house guest that came in yesterday...
but MY GOODNESS I'm already happy with the results !

As Don Istook stated I probably won't get better mpg at first since I will be enjoying the new performance, but can see where the increased torque will make the driving & mpg better !

It's like an engine transplant happened :)
Don't get me wrong stock is good, but this is "AWESOME" :)

Call your local Revo dealer today !

Easy to swap setup, and stores the original setup.

JBT,

Get your guest in the Q and do some driving and report back! LOL

One question. When I download their NA application guide, I only see a listing for the Q5 2.0 diesel. No numbers for the 211 HP 2.0T gasoline engine. I'm I looking in the wrong place? Now I see the A4 application. Guess thats it.


BTW. I'm up to 580 miles on the new Q. It's almost time to "boost the boost".

Congrats and glad to see you took the plunge JBT!

I'm going to wait until I put some more miles under my belt but I will surely get one of the stage 1 software upgrades.

Was thinking APR but I'll keep researching until I've driven more miles.

The website only gives a range for power increase. Did they tell you what your increase should be? The link you provided in almost 6 years old and I assume there are new DYNO charts.

Congrats again and keep us updated!!!

Yes, the sites are older links as I was too excited after the drive to breakfast this morning to find recent ones... but that link was for a 2.0T so it is similar...

this new revo tune for the 2.0T Q5 comes with stock - 91, 93, and 100 octane tunes standard.
Got this done WITHOUT any hardware changes or removal/shipping of ecu...
dropped it off before lunch and got a call back right after lunch that it was ready. also am getting the little obd switcher so I can change tunes as needed.

second drive impressions seems it downshifts less often as it has much more low end torque and can pull without downshifting...

I assume all tuners WILL be close,
my experience from the diesel tuning world is just the different tuners make the power in different ways, some more high end hp, some low end torque, some, etc...

this was recommended by a long time audi racer who (I would surmise) has tried them all :) and his 400 hp audt ttrs is stout !

will certainly let you know as more seat time and logging are gathered...
(have a 1/8th mile track about 15 minutes away that I can get some comparisons done for "you" :) if you are interested in straight line performance too)

Congrats on the upgrade! It's always good to get it done from a local dealer (for that extra peace of mind)...

My area has an APR dealer and the install required removal of the ECU, but all is great (power delivery is fairly smooth). The main attraction to APR is that I can change program without any additional hardware (it's done via the cruise control stalk).

I'm sure you will be enjoying the car a lot more now that there's more power on tap ;)

Forgot to ask....do you run the stage 1 with the VAG Dynamic setting for engine throttle?

hey John,

Did you do your tuning at DFW Audi, or at an independent dealer? I'm living in the area too and am interested in doing what you did. Could you give me a point to where to go for this? I have an 2011 2.0 PP

How much did this little performance boost cost?

more driving today and still pleased with just the around town behavior being more responsive...

obviously I don't have any empirical data yet,
(but hope to have within the next week after my guests leave)
but just impressions so far
(and those impressions are that it is well worth it!)

Heck - just getting to see the first audi ttrs imported int the states was a nice plus !
http://www.thetorquereport.com/2011/07/first_audi_tt_rs_finds_a_home.html

Still don't have any info on pricing, but I did look for a local dealer and Revo's US headquarters is about 10 miles from my house!!

Question, how does this affect your Audi warranty?

You do realize that I'm not associated with this company, just a happy consumer so far!
so here's the link where I found the pricing:
http://forums.audiworld.com/showthre...ight=revo+sale
$399 for four tunes stock - 91, 93, 100 octane
or $499 for the same four tunes and the 'switcher' thru 12-31-11
and for my dealer, it was one hour install time...

Since the norm around here is 93 octane,
that's what I will probably end up running...

the wife took it to work for the first time today...
let's get a report back from her to see if she ran into anyone's rear bumper with the new found responsiveness :)

re warranty:
as with ANY modification that is not the manufacturer's modification,
if the mod creates an issue, the mfg cannot be held responsible...
so the saying "if you want to play, you have to pay" comes to mind...

However, I can say I've had 4 different vehicles tuned for over a decade and 100's of thousands of miles without incident... and searching the forums you will find many people that have tuned their audi's.

but please get some miles under your belt before doing anything to ensure there are no underlying problems before you change anything.

I am also seriously considering some mods for my 2011 Q5 S-Line, specifically the 2.0T APR tune and a resonator delete. The resonator delete I have been told will be fine, as long as it's behind the cats it won't throw codes and it should create more of a growl, has anyone done this?

As far as the APR tune, my only major concern is that I have had some issues with the TCM, they had to reflash it IIRC because water had shorted something and that was causing that shudder that people complain about when rolling to a stop. I don't want to install the tune, then have audi tell me GFY because I voided my warranty. I like the program selector, because I would not want to run the engine hard ALL the time, just times when I want a bit more boost. If I do it through Pfaff Tuning, maybe they will be better about warranty. Going to pull the trigger within a week assuming I don't get cold feet. If I get it, I'll take my 2012 out beside it, drag them, and post a video.

So my questions...

Will I pay $500+ for a minimal tune then be spending $5000 on parts when I void my warranty?

Is a resonator delete a better way to go than to get a custom resonator?

Do I need to change the exhaust tips for a better sound?

Since it has program select, will I be able to use it sparingly since I run 50mi a day?

Will I be able to smoke a stock B8 A4? (They feel fast as hell when you get behind the wheel after the q5)

Ok, so it seems that none of these will allow the owner to return the ecu back to stock before taking it in to the dealer for service and them not being able to detect you were running a tune. My issue is my dealer gives all their customets a 100k mile powertrain warranty and I don't want to do anything to void that.

not sure who told you that...
but returning to stock was a prerequisite for any tune I got just as it has been for the other cars/tuners .

and I will be able to do that.


and to the need to switch tunes.... once I settled on a tune for my other cars - it typically stayed there for months at a time as the high hp tunes actually give me better mpg because they run so effeciently (as long as I drive sanely :) )


birdman - if you are having tcm problems, I would not add a tune.
and a 20% improvement is not minimal to me :)

any changes to your exhaust will not give you anymore than MAYBE a few hp, so if you call a tune minimal, not sure what we call an exhaust change :) change that if you want to change the sound..

not sure who told you that...
but returning to stock was a prerequisite for any tune I got just as it has been for the other cars/tuners .

and I will be able to do that.



OK, I guess I assumed that because you took it to a dealer to have it installed. I used a Superchips tuner years ago on a truck where I just purchased and installed it myself.

Will be interested to see how your mpg are affected.

No prob !

I will get some baselines soon so I can tell the difference other than the seat of the pants I've gotten so far....


fyi:
this was the deciding factor on my selection of tuners this im from revo:

Yes, $499 and the FREE SPS is actually the deepest discount we offer. We are already less expensive that the competition year round, and the Winter Sale is just some extra icing on the cake.

You get all 4 tunes, and the ability to control the switching in the palm of your hand. (If you're interested in the switching)

Here's a video of how the switching works for APR:
http://www.youtube.com/watch?v=g5oN-p5eKd8


Here's a video of how our switching works:
http://www.youtube.com/watch?v=tKScO1PQdv0


(These videos are for the B8 S4, but the procedure is the same for any year make and model VW or Audi.)

If you have a local shop nearby and are not that interested in switching yourself, or if you have a friend who has an SPS, or if maybe you just want to buy one down the road some time, you can still take the software with all 4 tunes for $399.

JBT,

That is sweet and simple. I've tuned and boosted all of my turbo's with no ill effects since 1984. . I am very interested in how your Revo tune works out in the real world. Please keep reporting back in future. No biggie if I miss sale. I've got to get a few more miles on my Q and let you be the test mule.:)

John

When you guys "tune" your cars, do you drive in this "tuned" mode all the time or switchback and forth? What are the reason for switching back to stock mode, for driving I mean?

I typically stay in tuned mode for a couple of reasons...
once you find something that fits you and your vehicle,
you tend to stay with it,
and once you get used to the new power, driving stock is like half your engine is gone :)

I did reset the trip computer to see how the average mpg was affected and it did what I thought it would...
Even with us running around town and using the new torque a LOT, it still came out to 23.7 on the display around town...

http://forums.audiworld.com/album.php?albumid=164037&pictureid=234605

so once we settle in and stop RACING around, mpg will probably go up...

on another note:
met up with wrestrepo to do some vagcom changes on his S4 and that is one nice, quick car !

I actually have a Revo dealer near me, and I asked him how the tune would affect the warranty. He said that if anything happens, it will only affect the warranty on the computer. He also said that they hardly ever look into the code since it's buried so deep.

Can anyone verify this? I'm so tempted to get this mod!

My dealer kind of confirmed it. He said they can't really tell what sw is running.

Well, I wish that were the extent of it....
but - in the event of an expensive engine failure or turbo failure -
Audi will probably look 'deeply' to figure out why and
especially so if there are decals and stickers saying you boosted it :)

so true, it doesn't affect your warranty...
unless the dealer and/or Audi decide it does :) :) :)

And no matter what your dealer says, if Audi decides not to repair your car, the dealer probably won't either .

So while tuning is generally considered safe if done by someone who knows what they are doing, it's still up to you to weigh the risks.

Heck, I've seen people ruin a stock engine with poor maintenance and bad driving !

@JohnBoyToo: Do you think the tune is worth it? I feel like the Q5 is sluggish, and I have hard time keeping it at a steady speed because it always wants to go one gear too high. Does the tune eliminate that? Also, is the Q generally more responsive? I feel a bit of a delay when I press on the gas.

So far I'm very happy with the results from the 45 or so hp and 85 lbft...
(and this comes from someone that tuned his diesel for $400 and got +150hp and +250lbft !)

but it makes drive like a different car - so yes it's worth it to me...
immediate response and loads of low end torque where we spend 90% of our driving.

(but, now that wrestrepo brought his s4 over with it's supercharged v6 and 333 hp - it took SOME of the luster off my tune!)

JBT,

I'm watching this thread closely for updates. I'm up to 740 miles on Q. I need a little more break in time and a little more positive feedback before I pull the trigger. Thanks.

what do you think the dealer selling the tune is going to say? it may void your warrantee?

At least he told me that it would void the coverage for the computer.

ya, if something really went wrong could you change it back to stock? it is software right?
That being said i'm in this vehicle for the long haul. drive 35k year. part of me would like to drive a Q5 with the mod. If its like you say I'm sure its fun. If it is just software to change the timing/boost on the turbo thats a hugh increase. SO then you have to wonder why the factory doesn't do it.
Logical answer , I would think, would be because it decreases reliability/longevity?
Mine is a daily diver, don't know

Part of it is emissions, part of it is because Audi doesn't want to make the 2.0T too close to the 3.2. But I'm not saying it won't affect longevity as more power equals more heat.

ALL mfg's typically under tune their engines as CinnamonQ5 said,
partly for emissions,
partly so they can ensure that each and every engine meets or exceeds their advertised claims of HP and MPG...
as well as to limit warranty repairs...

At the simplest level
"All" this is is new software and tables to change when boost comes on, how much fuel goes in when, etc....
so it is software only for stage 1.

Is the REVO Year End Sale over now? If it is, what is the normal price?

Just pulled the trigger on buying the GIAC software for my Q5 2.0T. Kinda an impulse buy since I was sure I would get cold feet if I thought about it any further. Thought about APR, but the tuning company also has dealers for Porsche Audi and VW so they stand behind the work they do and products they sell. Waiting for 2 hours until its installed, I'm excited!

I think regular price for the 4 tunes is $499, as the sale I got mine on was $499 WITH the switcher thrown in. or $399 without the switcher.

Hmmm, inferring it;s ONLY for the 2012's ?!?

No, mine is a 2011.

Wanted to get some good empirical data
(i.e. as good as I want to spend the time on)
so Dyno and drag strip are good benchmarks before and after ...

I just located a 4 wheel dyno locally and will be testing mine with and without tune to see the difference within a few weeks...
then maybe go to the local 1/8th mile to get some times for straight line performance...

(I know it's not a dragster - but seeing the delta helps !)

I'll look forward to your dyno testing results, JBT. I am going to be doing the same with my STaSIS tune in the next couple of weeks. A comparison would be good to see.

This might be the subject of a new post, but I'd also like to hear more about the magnaflow rears you put on. I've experienced a cat-back system and would be interested to know the difference in terms of cabin noise, resonance, etc.

Update:
Going for a drive through the country today to experience a bit more, but so far still liking it... sedate and smooth as stock when I want it to be and
stout when I don't want it to be :)

As far as the sound cp.... I considered the full exhaust replacement as I had done on many others in the past.

But I had such good luck with just a good flow thru muffler on my diesels at a much lower cost (and since I'm not after every last .005 hp increase)

I decided to go by the local muffler/propane/pc/taco shop :) that I've been using for all my project cars who don't have a problem 'trying' things and can usually suggest something close to what I want...

so just swapped the two rear resonators for the magnaflows and
it now has enough rumble to hide most of the sewing machine 4 banger turbo engine noise, but not enough to sound horrible like a little engine without a muffler!

Tried a video to let you hear the sound, but it's not loud enough to really be noticed other than by ear ! no drone usually associated with flow through mufflers...
and with the new tips filling out the cutout
http://forums.audiworld.com/album.php?albumid=164036&pictureid=233072
, think it looks pretty good for less than $100 total.

Apologies to the purist that think you shouldn't change anything on an Audi and for the banty rooster legs in the reflection :) - blame that on the track coaches!

Ok so, for <$100 you put on Magnaflow resonators and exhaust tips? I'm looking for ANYTHING that can turn the Q5's *putt putt putt putt* into a growl or a hum, and sound even better when I accelerate. What parts did you use, and where can I get them? Also, you just did cat-back correct?

I think the trick here is that JBT didn't do a full cat-back system and left the front silencer & downpipes alone...he just replaced the 2 rear mufflers. This is what I was interested in, and like the idea of getting some exhaust note adjustment without the resonating affect in the cabin that seems to go along with any full cat-back system that I have heard discussed here and elsewhere.

After installing...and then removing...a cat-back Stasis system (it was mostly ok, but had enough drone that it just drove me crazy), I am wary of trying anything else to adjust the sound, but for anyone wanting to try it it seems like JBT has the better idea.

Thanks for trying the sound clip, JBT. I'd love to hear it in person, but you're just a bit too far to go...

Is this what you used JBT?

http://www.ecstuning.com/Audi-Q5-2.0T-/By_Brand/M-N/ES1928333/

If not, what did you put on your Q5? I'll definitely do the same setup. Does it matter that I have S-Line (will the tips fit)?

Will get better pics and retry a sound clip as soon as the weather here clears but for now...

I really researched the full exhaust and cat back changes, but decided that I didn't want to change anything other than the rear two resonators and tips...
on edit - Here's a pic of the old parts with tips in the garage:
http://forums.audiworld.com/album.php?albumid=164036&pictureid=234698 (notice how these COULD have two outlet tips?)

My thoughts were that changing anything closer to the front, downpipes, center muffler, etc.. would cause drone in the cabin.

so the changes to the rear piping is only under the rear cargo area hoping it would be 'behind' us... and it was good - after a few more thousand miles to let the mufflers burn in it's still good...

Can't tell you the model # of mufflers and tips... lost the receipt and I've used that shop so much that I don't second guess what he suggest - his suggestions have always been good - why I keep going back to him...
he basically cut off the two rear resonators and tips and replaced with similar sized flow thru mufflers and larger diameter, longer slash cut tips.

as far as hp or torque increase - doubt if any difference - only wanted to mask the little 4 cylinder sound a bit and it seems to have...

Sorry to bring up an older thread, but I have a little over 3,000 miles on my Q5. Is that enough "break in" to get the tune?

Its all personal preference and probably moreso, confidence.

Some folks have got the tune before they ever drive the vehicle. Others wait a year to make sure nothing is wrong with the car before they potentially void the warranty. Some folks wait until the warranty is out.

It's all up to you and what makes you feel comfortable.

I also have about 3000 miles and itching to get a tune...but I will probably wait about a year. (About 15,000 miles). With that said, the more and more that I read about it and everyone's satisfaction with it, I may consider doing it sooner (especially if nobody reports back any problems with 2012 models).

I'm with you g8tor

As g8tor says - up to you...
Some dealers sell new stasis tuned cars right off the lot...

I've tuned some cars @ all ranges depending on how confident I was with the tuner...

I will say, so far, I am VERY pleased...

Got the switcher delivered
https://products.revotechnik.com/products/sps.aspx
and now it's time to go get some benchmarks for stock, tuned, etc.... at the track....

while I really can only test one of the tunes at a time versus stock since it is different octane rating tunes(stock, 91, 93, and 100), it will give an idea of the real boost. Will probably do the 93 octane testing as that is the prevalent fuel around here...

you know I will report back !

Now I'm a little worried. I've had no problems so far with my Q5. Perhaps I should wait? I'll think this over...

Eh....I wouldn't fret too much.

On my G35 coupe, I put in a Vortech Supercharger and went from like 224 bhp at the wheels to 385 bhp at the wheels.

And those 3.5 liter engines have very tight tolerances from stock and that thing worked flawlessly for the 18 months or so that I had it on there.

I installed it about 6 months into owning it. Never had an issue and everything that had issues was covered (never had any issues dealing with the engine or drivetrain).

If that little engine could take a 72% increase in horsepower without issue...I am sure this engine can take a software stage 1 upgrade of like 20 or so horsepower.

My only concern is making sure all my stock stuff works so the dealer wont have the opportunity to point fingers. After I hit the 1 year mark....I'll be ready for the power increase!!

After running my GIAC tune for a week, I've discovered the following

-Gas consumption is increased by no less than 15%
-Car is noticeably faster (I'm putting A4/5s to shame)
-Other Q5's are confused when they can't keep up
-The increased torque puts a grin on my face and a chill down my spine every time
-The car is a little bit stuttery when it's cold, but normal temp it's excellent
-Much better throttle response
-An S5 wanted me to drag him, I politely declined.

I'll keep driving it to see if I notice anything else.

I'm on my way to get it done today!

Good luck!

Apparently I can't get it yet. They need to take an image of the program on my ecu and send it to REVO because they haven't made a program for my specific model. They need to take into account the different features you have on your Q5 like if it has a sunroof, B&O, etc. They said REVO will send the code in about 5 days. I'm so angry right now!!

Get GIAC. It took 1:30 to install, and it was fast driving it off the lot, no issues either.

What a let down :( they did mine in about an hour and a half too... What is special about yours ? it's a 2 liter turbo ? what year ?

Really can't see where the radio has anything to do with the tune :)

but if they are customizing it for your car - kouwell !

your location says DMV ?
You are at the Dept of Motor Vehicles ?!? :)

DelMarVa is the peninsula on the eastern shore of Chesapeake Bay over to the Atlantic with beach cities such as Rehobeth Beach, Delaware and Ocean City, Maryland. Thus you heard the beach reports. Literally stands for Delaware, Maryland, Virginia. Nothing to do with DC

I'm at about 6,500 miles and haven't had a singly problem. I believe I got my Q5 tuned when it had 3,000-4,000 miles? Can't really remember. I love the tune, and can't imagine the car without it. I've also seen a slight improvement on gas mileage--I'm constantly getting 28-29 mpg on the highway and 22-23 in the city. Not much of a jump, but improved gas mileage + way more torque = happy customer. I'd highly recommend a tune.

Also, I haven't smoked any A4s yet, but I've definitely passed some X3s and RDXs on the highway.

Thanks Guys. I am especially interested in Revo stage 1 with SPS controller. Burdoogo, it is great to hear your positive feedback after living with tune for a little time. I gather Audi didn't give you any trouble at your 5k oil change/checkup. Did they do any software updates? Just wondering if they were able to see the tune and if they said anything about it?

I had the SPS controller, so I just switched it back to stock for my 5,000 mile checkup. They had no idea I got it tuned. There was no software update I believe. I talked to one of the techs, and he said it's just routine maintenance stuff.

Here's a question: is the stock profile in the controller factory loaded by the manufacturer or is it loaded from your stock vehicle when you get it?

I'm not really sure. I would call REVO, or ask your REVO dealer. Sorry I couldn't give you a better answer. Anyone else know the answer to this question?

JohnBoyToo,

I plan on doing this custom exhaust to my 2.0t using Magnaflows. Do you think it'll be too loud?

Remove both Secondary silencers and Primary silencer. Then replace the Center silencer with a Magnaflow muffler. Add two 3.5" or 4" tips.

We replaced only the two rear silencers with flow thru mufflers and it seems to be a BIT louder the more miles we put on it...
Depending on which muffler you chose either it will be fine or sound like a four cylinder with a loud exhaust :)

but if you look at most exhaust upgrades, it is just that - remove the restrictive stock exhaust from downpipe back and replace with a good flow thru muffler and tips ...

as long as your installer takes care,
all parts taken off can be put back on :)

I have the two resonators and tips in the garage overhead bins !

make videos so we can hear it

Sorry - been out of pocket - got two new toys that's kept us busy!

Nice toys! I'll definitely take vids and post after I get it installed. Enjoy your new toys.

It's true what they say, everything's bigger in Texas :)

Jbt, Did you dyno it yet?

No dyno

lost interest actually as the wife drives it all the time and
I'm busy with the new toys :)


but some had asked for what exhaust changes I made with the magnaflows:
here's a video of them where they replaced the rear resonators:

and here they are in action with sound and fury added :)

Just thought I would share this with those of you considering software...

I was having an issue with my LED DRL on the driver's side shutting off randomly so I took my car to the dealer that installed my GIAC software so they could check it out, as I have been very careful about not voiding my warranty.

As it turns out, Audi has been using the new system that flags tuned cars for some time now (more than a year) under the noses of dealers. Needless to say my engine and power train warranty is voided in Audi AG's eyes with a TD1 code IIRC on my car, odds are you've been marked too. Luckily for me the dealer that installed the tune personally stands behind their work, and will make sure I'm looked after if anything goes horribly wrong.

Just be careful guys, Audi doesn't like these software tunes even though they unlock the car's true potential. If you do choose install a tune, make sure you do it through a dealer or company that will provide warranty, or at the very least, peace of mind.

Has anyone actually had a warranty problem denied as a result of TD1 flag in a Q5?

[QUOTE=Needless to say my engine and power train warranty is voided in Audi AG's eyes with a TD1 code.[/QUOTE]
Did Audi actually tell you that your powertrain warranty is voided?

I left my car in to fix a leaking roof seal and have just had a call from the Audi dealership to say that they have found an unusual code in the ecu programme!!! and have now flagged the car as being tuned! Apparently the Isaac Agnew Audi dealership in Northern Ireland undertakes checks on all cars that have people have chosen not to purchase from them – very kind! Not the sort of people you want to be going to for warranty work if your car is tuned.
It is also disappointing having had previous assurances from REVO that it was almost impossible to identify their tune. Beware!

Do they go looking for these tunes every time you bring your car in? It sounds like they only find the code when you bring it in for some sort of repair, but not when bringing it in for regular maintenance (interval oil changes, etc).

I could be wrong though, but I hope not.
