Default PCM Flashing
Hey Guys. First off thanks for any and all input.
Im putting a 2004 escalade back to stock however the PCM is tuned by a Dyno shop for 42 lb injectors 12.5.1 408 stroker.
CAn i just flash this with a buddys lotus diagnostic tool back to stock? From what im reading tuners lock in their tunes to avoid this correct?
Can i swap in a junk yard computer and call it good?

Again thanks all!!

Depends on the tuner, some of them lock it but most of the reputable ones don't.
