My friend's 330 vs my ITR.

From a standstill, even with his RWD, I still get a better launch than him. He loses by about a car and a half.
All 3 runs from stand-still have about the same result.

From the freeway starting at approx. 70 MPH. I think he always started to mash first, but whatever.
He definately pulls harder, but 2 of the 3 times I came out in front.

Anyone have any idea why? Or is this a legit outcome?
