i was thinking about getting the uprev unit and getting my friend to teach me how to tune. He makes ALOT of money tuning cars with hptuners. I understand the basics of tuning but i wanna learn more. Been reading non-stop about tuning the last few days. Make it a hell of alot easier to tune my car when i add parts to it, then it would be to go to a shop, may a bunch of cash, then get a new part and have to go back.
