Ok, so if some of you remember I got a jet stage II chip a while back, maybe 2-3 weeks ago and it wont work with my car for some bizarre reason. So ok, I was like f#$% that I'll get the hypertech thing its better anyway. So I buy one from some guy off ebay at a decent price ($200) and I receive it, its still under raps and stuff. So I am like all happy and whatnot, I want to "power program" my ecu so I plug it in, follow the directions, it downloads a bunch of stuff into itself...then it states this "Calibration not found". I call hypertech and they are like, you need a receipt. The thing is I don;t have a receipt, a got it new from some guy who bought it off of ebay but he didn't give me the receipt. Soo now, the hypertech is useless, the jet stage 2 chip is useless unless i want to spend $600 and I still have no more power then I did 1 month ago. All in all I spent $379 dollars on two items that arent gonna help me in the least bit, unless I spend even more money. I wonder if anyone here has run into this same frusterating pickle, and has anyone solved this problem successfully??? if so PLEASE LET ME KNOW. I want to erase what is on the hypertech III, does anyone know how to do that?? PLEASE HELP. I am frusterated and angry that neither product works and I am still on square 1.
