Just load that tune to return it to standard, which will work fine as long as you have no mods (usually even an exhaust system requires a tune). Keep in mind that each flasher unit is locked to a unique Vin number, so the flasher has to be returned to be re-programed. *The flash tuner can be changed over to a new vehicle, it must be cleared using software available from CAPA. This process can only be performed 5 times. Then it must go back to SCT / USA for a Reset.
