stock. This is accomplished by connecting the tool to the vehicle, selecting Performance, then
‘Original Backup’ as the tune to install, thus returning the PCM back to stock. If you are unable
for whatever reason to restore the stock tune to the vehicle, please contact technical support
at the information below before proceeding.

serial cable.
