  1. Dealership will not void your warranty for tuning if you don’t go into the dealer acting like a jerk. Most if you are honest will go out of their way to help you. Unfortunately if you get into a situation where engine replacement or transmission replacement is necessary GM will require the dealer to send in the calibrations to tech support and they will decline your warranty and put a warranty block on your vin number.
