PCM reflash question I've got a 1998 Trans am with a performance cam. It was tuned a few years back by MTI in Houston. I think this was before HPtuners was available, so maybe they used LS1edit or some proprietary software? Anyway, I am demodding the engine back to stock and I need the stock tune, and I don't know anything about tuning. Can it be reflashed by a GM dealer, or will I need to get a new PCM?
