    Contact your tuner.

    They will need to set up the Autocal for you to have the required BBX files and PIDS

    I contacted GDP Tuning today and the tech sorted out the problem. He also fixed another issue with my switch, the little ring with the tab was in the wrong location. I have a switch with High idle so the tab needed to be between 6 and 7 not 5 and 6. Voltage reading is good and all tunes seem to be working...but i did expect more grunt out of performance and rampage tunes. I like the street tune the most.
