Welcome to the bad delete club!.

This is the typical hack-n-slash garbage-can delete where some complete moron thinks that if they do as little as possible and only block codes, then jack with the turbo to try to make it run better.. and hope there is magic fairy-dust leprechauns inside the the ecm that will make everything all better. -- What a damn mess this one is.. is all I can say.

Thank you Rawze, that gives me a point to start and to pitch to the truck owner. That is pretty much what I expected to hear, not that I knew what the issues would be but that is was done improperly. With the lack of traceable history and the way this thing has been cobbled up in other places, I didn’t expect the Ecm work to be any better. Im open to suggestions on how to right the ship?? I’m working through the Cal/Insite programs and learning, but it’s a heck of a steep learning curve! Lol!
