...but from what our dealers have told us as well, is in most instances GM will honor any work done to the ECU or power train if it was done by one of their techs. If a tune is done by anyone else you can be SOL..
With that said, I have never...EVER heard of GM tuning out AFM. I would be very, very interested in contacting my dealer as well..
