I am from "old school" when tuning was done by actually adjusting the carb or distributor.

I want to try my hand at "tuning" my 04 GTO. What would be the easiest 2-3 manufacturers to consider purchasing and learning to tune?

 

First GREAT MOVIE, now on to the question at hand. If you are looking for a hand held programmer then try the Crane Power Programmer. If you would like ultimate tunability then try out the HP Tuner software. Cheers !!!
