I really want to get into some OBD II tuning and want to be able to tune my wife's '00 Grand Prix. I found that EFI Live does not support those controllers and has no plans to so that leaves me with HP Tuners and JET as options. I like what I see with HP Tuners and was gonna go that route, but I have been looking for a good deal to save as much as I can. In the process of looking I have found a couple of the JET tuners that I can get at a discount. Before I go spending that kind of money, I still wanted to get some opinions from people that have used it and possibly HP Tuners as well. I don't see any major limitations of the JET tuner so far, but I know that there's always a good chance for disappointment when you buy an unfamiliar product. Thanks in advance,

Phil
