UNINSTALLING  RETURNING TO STOCK
What does this mean?
“Uninstalling the tune” and “returning to stock” are different ways to describe the same thing: writing the original (stock)
information to the engine computer so it uses the settings that it used before you installed your GT. Doing this also sends a
signal to the GT to let it know that it is no longer installed on a vehicle, which will allow you to install the tune at a later time.
The GT will not allow you to install if the tune has already been installed on a vehicle.
When to Return to Stock
You should return to stock in ALL of the following situations:
• EVERY TIME you take your vehicle in for any type of service. It is a very common practice for the engine computer to be “ashed” (re-
programmed) during all types of service, even routine maintenance. If the tune from the GT still installed when the engine computer is
ashed, it can cause problems when you want to use your GT in the future. See page 38 for more information.
• If you want to install the GT on a dierent vehicle. For instance
If you have a second vehicle and want to try the GT on it. The GT can only be used on one vehicle at a time.
If you want to let a friend try the GT.
If you have decided to sell the GT to someone else.
• If the battery is having problems and could possibly go dead.
• If you need to disconnect the battery for any reason.
IMPORTANT NOTE: If you do not return your vehicle to stock, you may have to call in to technical support to have your GT reset. There is a mandatory fee for this
service. See pages 41 and 49 for more information about the reset fee and contacting technical support.
