Sent an Email to Kevin Brown at BD about this, will see what they respond, But I will agree, you buy something you should be able to use it on any vehicle you own as long as you only have it installed on one vehicle. If this is not the case they will be loosing a ton of business, a happy customer tells another person to buy the product, a disgruntle customer tells 10 people not to buy the product, in my case, 100 people will know not to buy it. But till I get an answer from him direct, I will keep my voice quiet. Will post the response as soon as I get it.
By the way, this is the information I have found in there manual for the Hemi GT +.
GT for Hemi Plus
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 45 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. Make sure to connect a battery charger while returning to stock to prevent
any complications that can be caused by interrupting the GT while it is returning your vehicle to stock. See page 34 for more information.
This is from there pdf you can download here, I would thing that if you bought the Unit and the Instruction manual stipulates that information and if you presently download that from there website they would need to honor that info since the unit was sold with that information implied.
