Bench racing with Pink Pony Power thats what...
So we had a group of B6/7/8 S4/RS4 guys out to the local dragstrip on Good Friday. It was a pretty perfect day with nice cool temps, but some sun to keep us comfortable. I believe it was 50-55 degrees most of the day. Strip was open from 11am to 4pm.
Toronto Motorsports Park
Density Altitude at 11am = -488 feet
Density Altitude at 4pm = +281 feet
Basically perfect conditions. All the Audis had great traction and ran decent times.
12.13 @ 114 ilspazzaneve/jspazz B8 S4 DSG APR V2 100 tune, pulley
12.2 @ 113 81bear, B8 S4 DSG APR 93? tune, pulley, HFC, Milltek Catback, LW Wheels
12.35 @ 113.8 turbobaby, B8 S4 DSG Revo 93 tune only
12.75 @ 108.3 sakimano, bone stock B7 RS4
12.88 @ 109 seinsmeld13, B8 S4 DSG GIAC 91 tune
13.19 @ 104 boravr6 B7 S4 MT6 JHM 93 tune, 2.5" fullback
13.42 @ 103.9 bangoman B6 S4 Avant MT6, JHM 93 tune, Magnaflow catback, JHM LWFW
Random cars we saw, not sure who:
* low 13's @ 110, C63 AMG
* high 13's at 108-9 - unknown, E93 M3 cabriolet
* 14's @ 101-ish - unknown, B8 S5 (4.2FSI)
* low 15's @ 98 - unknown, presumably stock Pearl White B5 S4??
So as you can see just about everyone ran decent times. The GIAC post that was famously all over every forum a few months ago showed a 400 whp dyno plot for a GIAC 91 tune only B8 S4. So what happened? The GIAC 91 car at the strip ran half a dozen times, and was 12.9-13.0 all day, at 109 mph. Car wasn't broken. Driver wasn't complaining. Conditions were just fine.
We even got one run in head to with me in my B7 RS4.
RS4 (stock) 12.90 @ 107.7 (best was 12.75 @ 108.3)
B8 S4 (Giac91) 12.92 @ 109 (best of the day)
So the question is...what happened to 402 whp, GIAC?
The other question is 'WTF IS REVO DOING?'...car was damn strong for just a tune. The owner ran 13.0 @ 107 I believe when we went to the same strip last year. He picked up 7 tenths and 6 mph with just a tune. That's amazing.

I dunno, but after reading all about 1/4 mile times and tunes on all the boards for the past year+, I'm even more convinced than I was previously that DSG + just a tune (for everyone but REVO, apparently) results in 12.7-12.9 at 109-ish.
Voltron ran that with APR, I've run it with STaSIS and now Seinsmeld has run that with GIAC.
So, rather than my time or Seinsmeld's time or Voltron's time being "outliers" for tune-only cars, it seems to me that our results represent the norm.
Now, as to REVO's results, I think the question is still open as to how they get there....

But I'm glad to hear Revo is doing well

Fuel and DA need to be part of the equation... Your estimates are probably accurate for 91 fuel and average DA... someone on 100 tune in -1000+ DA will run much faster than 12.7 IMO... Revo gets there by running more timing on their 91 and 93 tune and not dumping any boost...
the rest of us mere mortals are forced to live with our cars on pump gas for the most part. And on pump gas, the tuned cars generally run mid-high 12s rather than stock cars running high 12s to low 13s . APR/GIAC/Stasis 91 are all in the upper 12s. APR 93 a bit quicker getting into the mid 12s. Not sure on GIAC 93...data is spotty.
REVO is in another league. Or is playing another sport.
The REVO guy who was with us Saturday made an interesting comment. After running 12.3 a couple of times, he came up and said 'I think I'm going to shut it down...don't want my car to blow up! Who knows what these guys are doing!'. He was partially joking but it didn't sound very comforting lol.
It should be noted that he also had lightweight BBS (proper) wheels.

So intake and exhaust might have helped. Lets pretend they add 30 whp. That means the tune alone would push the car to maybe 360-370ish? 12.9 @ 109 isn't 370 whp. Heck my RS4 ran 12.75 @ 108.3...down 1 mph vs. the GIAC 91 car. My car might dyno 320 whp/280 wtq. If the GIAC 91 tune makes mid-high 300s whp and 350 wtq or so, I'd expect to be 5 car lengths behind the GIAC car. My car weighs about 3920 lbs with a full tank and I am 6'5" 240. DSG B8 S4 weighs around 4000 lbs and the driver might weigh 180. So weight was almost the same...maybe 20 lbs (we were both less than full gas).
I don't think his car is weak...I think we just finally got some good data on the 91 tune that wasn't from the guys selling it. Z was right...APR, Stasis and GIAC 91 tunes all deliver about the same times. APR91 advertises a modest WHP number that is nothing like what GIAC is advertising...but performance is the same.

I'm not disappointed in GIAC in the least bit... in fact its awesome.
Just wish I had some time to get to do some real logging and get to a strip.

That's a bit odd. Now we know why they didn't show any actual performance testing for the 91 file.
The 91 file marketing was basically directed at the California market where 91 is all they can get. Much of the west is limited and can't run the 93 file. So, the 91 file was held up as this worldbeating 400+whp monster...when we now know have some performance that shows otherwise.
