how much money do you want to spend... i no a guy that got the hptunners for his laptop and put the software in it. and he had no knowledge of how to do a tune. it is a step by step procedure and as long as you have a baseline to go off of you can do a self tune. all he did is took another persons tune and basically did it to his. and his car runs fine. he also had to tune his gto for the cam and headers he installed. so that makes it harder. just make sure that is what you really want to do. as you could possibly loose your drivetrain warranty because of it...
