    open your tune. Press f1, working with vcm editor-parameters gm-operating system. Read application procedure, pay particular attention to step 8. Also, search the forum for how to enter SD mode.

    Pay particular attention to the engine diagnostics section for the MIL's, entering the incorrect will have severe effects to the tuning process and make things worse. When you get to where your comfortable with the tune save it as a SAFE TUNE, then you will have something to revert to or compare as you go on, just my two cents in learning. As stated above (very helpful member) read, read and do more reading as you go on.
