I flashed a dsp5 tune I built for a 03. Into a 02. The truck will idle for a few min and shut off. No codes. Put truck in gear. Give a little throttle will kind of lunge forward and drive a little then shut off. Put stock tune in the truck and runs fine. No shut off issue. Any help would be appreciated. Thanks
