I have a friend with a LBZ that wants the LB7 rumble with his truck. He's using a PPE tuner right now though. I was curious if I was to modify the stock tune with just the vane position and then let him use his PPE after that would it just overwrite it my changes? I know I could just have him flash the tune into his truck and then alter the vane table, but that would be worth it if he wants to change the tunes with the tuner.
