    So for those with the Cobb AP, do you guys uninstall it, load the stage 0 map, or just take it in as is???

    I haven't had to go back to the dealer (yet), but if/when I do I will uninstall the tune.

    When I go in for just an oil change and I know that they are not doing anything else, I leave it in.

    Tuners for other vehicles I've had, have warned about flashing the ECU with the tuner installed. They claim if the dealer flashes an update to your vehicle, it will erase your tune, and likely cause your tuner to "lock itself," since it was paired to the ECU before the update, and won't be after. Not 100% sure of the truth to all of this, Diablosport sells a cap that says "DO NOT FLASH" for the OBD2 port. Maybe someone can clarify?

    Dealers or any shop for that mater are not allowed to do anything to your car without telling you first.
    Only a dealer can re-flash.
    If your service writer tells you there is a PCM update then uninstall the tune.
