Need help with tuning my '86 from scratch..
I just bought an '86 coupe A4 z51 AL head car. It is all stock with 127k on the clock. I have been through Gordon's c4/zr-1 classes 2.5 years ago but I have had c6s since and I have forgotten most of everything I learned.
My car is slow to start and does miss a little at an idle. I want the most performance I can get with stock induction, cam, and exhaust.
Where do I start? I really would appreciate some help brotheren......
