Madz28

[TheBandit]

Alright so I've narrowed it down and I'm going to go with a MadZ28 tune, since i can't afford a dynotune. I'm going to send him my information on my car and everything but my question is if i have log files from datamaster I assume I should send them and it would help him tune my car.

Also where do you guys suggest i get the lt4 knock module from and what brand i get?

thanks deadtrend. If i can't find a used one i'll order one. I'm assuming they'll rape you on the price if you go to the dealer?
