Engines/Performance/Tech Questions
I have an 04 Colorado 3.5L I5 with a K&N air filter, aftermarket exhaust, jtr header, ported throttle body, and an E fan, should I try to take it to get tuned on a dyno or buy a chip and if a chip which one? I'm just unsure of what to do for a tune and figured id ask as I cant figure it out...
