After your vehicle is returned from the dealer, plug your Power Programmer III back into the under-dash diagnostic port. The Power Programmer III will detect that the calibration has been altered by the dealer and will ask if you wish to reinstall your tuning options. You will not lose the capability to program your vehicle with your Power Programmer III if the dealer updates your calibration.
