    Tuner Lock Removal E38 ECM

    HI EVERYBODY

    I'm working on my car GMC sierra 2008 I would like to read the tune file but unfortunately, the previous owner tuned the vehicle and put a lock on it. How to remove the pass key ? or how to reflash it? I use a GM MDI but not working any suggestions?

    Regards
