So I've run out of credits for my HPtuners and I've recently bought a new 98 GP. I'm wondering, I have a tune unlocked for the same year GP that I used to own but have sold. How sensitive are the cars to a pcm with a different VIN? My question is if I do a full write with the tune from the other 98 gp to this 98 gp so I can tune with my hpt, will it bork anything up? I would try it if I had a spare PCM but I don't have a spare handy right now to test it out.
