I installed a custom tune under the calibration ID number 0509450AH and when i tried to go in and make changes to the tune my predator gave me the message "Calibration ID 0509450AO not supported". Now i know this LOOKS like the pcm may have been reflashed by the dealer, but it was most assuredly was NOT. I went from installing the custom tune to (5 minuets later) Calibration ID not supported when trying to go in and adjust parameters. I cannot install the original back up to update the tool so i can start fresh.
Are there
