i have been wanting to tune my car, but i dont know where to go. do i just buy the diablo tuner , or can i find a place that has one and let them do it? if i find a place that has one, how much is the the cost? also i know a guy that says he has some sort of tuner that he paid over 1000.00 for that works for many cars including mine. should i let him try it or is that a bad idea? i dont know the first thing about how this work, can anyone give me an a- z acount on how this is usually done? thanks for the help guys.
