Best shift RPM on A4 with 3.43 gears for 1/4 mile Hi...new to the site so appreciate everone's opinion. I must say I've referred to this site often and have learned a lot from everyone. Here are the dyno numbers on a Mustang Chassis Dyno for my 2001 full weight (3900 llbs with me in it) Conv Z28. Q1. Based on my engine build and the 150 nitrous shot on a 3.43 A4 where should I be shifting for the best 1/4 mile times?
