Car: 2010 L99 SS / RS
Mods: Stone Stock w/ Nothing added but the GMS/TTi TT Kit
Turbos: The only ones you need PTE6265
Wheels: Stock
Air: If I had a dime for every time I read how the air was bad so the dyno numbers were off....blah...blah
Numbers: 575rwhp / 575 ft/lbs
Not sure why it takes others 2 or 3 days and 30 to 50 tries to get a stock tune figured out

The auto trans cars don't make the power of the manuals for primarily 2 reasons:
Displacement on demand is a power sucker (only found on the A6 to date)
and 2, the cam profile (because of the displacement on demand) is not as forced induction friendly.
At the same boost with the same kit on the M6 we see 640 hp and 600ft/lbs.
Like we said, if you have the turbos figured out, there is no need to play musical turbos
Dyno graph goes up shortly
