I have the hope that someone has more insight on this. :
TracKey is saved as part of the stock tune in the XCal (quote fromShaun AED). Ford Racing has locked this tune and so far, no one has been able to break the code. Therefore, when the car is returned to stock AND this is essential : the only CAI that will allow you to alternated between the stock tune with the added TracKey tune from Ford, that is activated only by use of the Red Key is the Airaid CAI that comes with the "venturi insert" or sleeve. # 453-174. When insert is installed then it mimics the air flow of the stock intake box.
It is my understanding that if you try to use the Red Key with any other CAI, then it will work, but throw codes and how well it will work, I would prefer to not find out.
