Here is a letter that we received from Shelby Automobiles Inc. about a recall that has been issued and a possible problem if the dealer does not reset it right. It is possible that this recall has already been performed on your car and they made the mistake. I hope this helps, because there is no way that a GT500 will only perform like a 05 GT. It should run circles around it.

Attention Shelby Owners - IMPORTANT INFORMATION
Owners of Kenne Bell, Paxton, and Wipple superchargers
This information has to do with the Ford recall notice with respect to passenger side airbag. If you decide to take your car into your Ford dealership for this recall, they will need to tap into your vehicle's computer to correct the problem. They will need to re-program the RCM (Restraint Control Module). It takes them a very short period of time and you should be on your way without incident.
Here is where it gets tricky. If by accident the technician goes into the PCM (Power Control Module) instead of the RCM, they will essentially replace your existing power tune with whatever is in their programming module. If you have a Kenne Bell, Wipple, or Paxton Supercharger, then you have a vendor-unique tune. If the technician accidentally wipes out your unique tune, Ford cannot re-program it without obtaining the unique vendor program direct from the supercharger vendor.
If you encounter the worst case scenario, and your program gets wiped out, have your Ford dealer contact Shelby Automobiles Inc. directly. We in turn will work between the Ford dealership and the respective supercharger vendor to insure that they receive the tune needed to re-flash your PCM. DO NOT have the Ford dealership contact the supercharger vendor directly. The MUST contact Shelby at the following telephone number:

Please take this communication to the Ford dealer if you are intending to act on the passenger side airbag recall notice.
