right now i have a milled head that raised my CR to about 10.5:1, shorty header, high flow cat, 2.25in exhaut from flex pipe back, cam gears, and a pulley. I bought a used diablo chip that i put in. it took my governor off but i dont know what kind of programs it has on it. what is the best way to tune my car? send the chip in? (where do i send it? how much does it cost?) or should i get on a dyno? or buy something else to tune my car with like a Xcal2?
