Bah so it sounds like HP Tuners doesnt have the stock GM tune then? I thought they did....does anyone have HPT? Could they check for me? It would just make my life a lot easier if i could use HPT and put on the GM reflash, that way I could put the kit on in the garage at my parent place, insted of in my driveway. And if I did use someones tune why do I have to use there vin? Cant i just copy there tune but not the vin?
