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 “flashed” (re-
programmed) during all types of service, even routine maintenance. If the tune from the GT still installed when the engine computer is
flashed, 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 different 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.
