I think this truck could be a 06 LLY but when I connect to it to scan it won't show data for a lly. Only for LBZ, all other data is correct and all the dvt controls work, just desired rail is crazy.

Thats what i figured, i can't seem to find anything wrong with the truck other than the desired rail. it came to me expecting it needed injectors but they seem fine, can't figure out whats causing it to run rough and smoke.
