Hi All. New to Duramax and Forum, but have been tuning (consumer side) Fords for 10 years and never had any issues. Finally converted to a Duramax for my farm truck and bought EFI Live AutoCal V3 and a custom tune. Followed the directions to unplug throttle sensor, programmed the tune then fired her up. Ran fine for about 2 minutes then shut off. I can start it up every single time immediately after and move the truck so long as I dont use the accelerator. I can shift and idle will move me around driveway forward and back but as soon as accelerator is touched, it shuts off. Tuning company sent me 3 tunes and all the same behavior. 10 days now without a working truck because no stock was available due to no read ability on LML I guess. Anyone else run into this issue or know the best way to get my truck going again? Thanks so much.
