hello, i have been having this problem for severe months now. i tuned the car at church and took it home, i went to the track the following weekend and the car kept shutting off once i got in high rpm range, it would shut off and back fire really badd. so after me and my crew could not figure it out we took the car to retune and i think they said the last tune was off because the template's or graphs were different? and the only thing i did between the first tune was send in the kpro to get the data logging added. so i had to pay to retune the car from scratch again. and it ran fine on the dyno, but we had to stop tuning cause we had clutch problems. then once i got the new clutch in. i tested the car and there we went again. the same problem, the car shuts off and back fires when i reach 7-8k. no matter what i do. i tried leaning in to the throttle and it still does it. so a am stuck again! any help? i have checked the wiring harness over and over so i doubt that is the problem. over the weekend i heard of a couple people that are having this problem? any ideas?
