Ok I dont know if anyone has said this, but I will. Good choice on the Audi, the Audi can smoke the Nissan in the 1/4 and anywhere else it wants too. Couple of things tho, you know that quattro has NOTHING to do with the tranny right? That just dictates All-Wheel-Drive. And what you need to go get is a Chip for that thing, either from APR or GIAC, I am not sure if Upsolute makes one for the A4 or not. But I have a VW Wolfsburg 1.8T chipped, and now I have 210/240, awesome.
