I've done a bit of searching through the forum and haven't really found what I'm looking for, so I'm now asking:

How about some chip guidance?

It's my understanding that I can gain about 50 hp and 100 lb-ft of torque. Correct? With stock exhaust?

What about adding and exhaust system - how much more of a gain?

Does the tranny hold up?

Does shifting speed improve?

What does it tend to do to gas mileage when you chip and RS6? If I drive like a normal human being (not to terribly likely), will I retain similar mpg that I'm seeing now or will the chip hurt me across the board no matter what? I've averaged 14.91 mpg since I purchased the car (I keep records of all my fuel usage)

Is there anything that will adjust the front/rear bias so I can help rid the front end push? Dropping back to only putting about 10 to 15% of the power to the front would be great.

Thanks in advance for any advice.

An RS6 & an R8 in the same garage - It doesn't get any better!
