Well, i finally got around to putting on all the parts i had stock piled in the garage, 2.76 upper with 4 idlers, JLTcai, Afco Heat exchanger, NGK TR6IX plugs, XCAL 3 with tune from Rick at Amazon, etc. Anyway, is there anyway to tell which tune is loaded into the car? When i loaded the tune from Amazon it showed that it uploaded 100% then it said "error cannot open file". I tried to load the stock tune back in but it says it doesnt recognize the vehicle. I called SCT and Amazon and am waiting for their replys, just wondering if any of you guys had any insight into this. Thanks
