my buddy's truck was a great running truck until his truck started throngs cods. he had to remove somethings and he bought a eflive tuner thinking it would work. well he didn't read every thing and he erased his ecm I'm not sure if I can use my hp tuner on it because he erased his ecm. I do know that I'm going to need a stock program for his truck but I'm not sure what I have to do so some help would be nice if I could get some.
