So i have a buddy who just recently bought a 2002 audi s4. He has a couple things done to it like an intake and a tune and downpipes i think. Anyways we go cruising every sunday night and i decided one night to give him a run from 60. Right now i have a CAI, zzp 1.0pcm, zzp hv1 tb, ported manifold and downpipe. From a roll he pulled about a car lenght on me pretty quick but didnt go much further than that. Anybody have any suggestions as to what would help me take him down a notch? Im getting ready to put on a LS1 throttle body, 3.5 pulley and im having it tuned on the dyno by a local shop. Will those be enough?
