I believe the hypertech is only calibrated for the 3:45's....you will have
to play with the tire size. There is a formula out here on the forum somewhere....I believe... :)

Sounds like it'll work. I wish it was that simple for me - I have to change at least 2 gears at the back of the tranny when I do mine... :(

You are in there. A4 folks pre 94 should just do the gear swap in the tranny as well as the VSS. Contact 18carfan for the parts real cheap. Easy job....love the results. :yesnod:
