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 40 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.
What if I Don’t Return to Stock?
Here are some common examples:
• If you take your vehicle in for service, they will “flash” the engine computer. Even if you ask them not to, any dealer or shop will do this
automatically – it is standard procedure for any vehicle they see and they really can’t help themselves from following this ingrained
habit. What they are doing is actually writing an updated file over any information that is currently saved in your engine computer. This
includes the tune from your GT, so basically the tune is no longer installed and you will not be able to use the power level settings or any
other options – but the GT doesn’t know that, it still thinks that the tune is saved to your engine computer. Unless you go through the
uninstall process with your GT, it will still show as installed and will not allow you reload the tune on your vehicle or on any other vehicle.
The only way to resolve this problem is to contact technical support and have the GT reset – there is a mandatory fee for this service. See
page 36 for more information about the reset and fee.
• If you sell or trade-in your vehicle you will not be able to install your GT on another one without calling technical support to have the GT
reset. See page 36 for more information about the required fee for the reset service.
• If you sell the GT to another person without uninstalling the tune from your vehicle first, they will not be able to use it. You will probably
have negative consequences like an upset buyer, having to refund the purchase price or cover the cost of a reset, a negative review, and
bad karma. See page 36 for more information about resetting the GT and the mandatory fee.
By now, you may have noticed a pattern: if you do not return your vehicle to stock and something happens to your engine computer, you
will need to call and pay the fee in order to have the GT reset. Page 36 has more information about the reset process and the required
fee.
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 36 and 44 for more information about the reset fee and contacting technical support.
