I think you guys are giving numbers as if he had a 6 spd. WIth the a4 you should expect 400 - 420. hp.

get the fast ported if you can spare the extra coins.

my buddy with that combo, 6 speed & the MS4 cam, & TSP duals made 455/409 through a 12 bolt & slicks. But he has a electric WP and no power steering so that frees up some power there.
