Do you have a scan of the results. 11.5 is certainly not what I was getting.

It would give him a chance to drive one. lol

Then just for the heck of it take it to those Top Gear guys in the UK and have The Stig run it around the track as the official Camaro V8 time..I think by then GM will do something about your speed..

No doubt.

I'm not sure why GM is commanding such a rich air/fuel on these cars, the LS3's are typical GM rich in the 11.5 to 12.0 range, but the high 10's to low 11's on the L99's reminds me of how bad they do on the stock tune on the trucks. The timing is also very weak on the L99 factory tunes and there looks to be a lot of gains to be had on these tunes. Once I get one on the dyno instead of just a street tune I will get some before and after numbers up.
The six speed auto is good for 20 to 22 % drivetrain loss at least based on Vettes and STS-V's I have dyno tuned. Only the M6 is going to give you a 15 to 17% loss. The A6 is pretty heavily built for strength and that eats up power to the tires.
Really there is nothing wrong with your car, that is just how it is programmed from the factory and the dealer has no way to fix that.
Something in the 320 to the tire range is what I would expect one of these to make to the tire stock. 400 X .8 (just a 20% drivetrain loss) is 320HP.

So you think my mixture is satisfactory?
