Mail Order PCM?
dont waste your money, its like going to the doctor for surgury without a diagnosis or him examining you first, would you do that? nope, each car is different. there is not one tune out there that will work on cars with the exact mods. and how will they know any vital information without data? not bashing on the shops that do this, i am sure if you went to them they could do a damn good just, but wtihout seeing the car i think its a waste
when you break the engine in you want it to be a pretty good tune, you dont wanna run nasty rich. some shops do great work and others charge you for a bunch of bull ****. depends where you go
