Do you still have the red key? I am still trying to understand why this Red Key that is mostly used on the Boss cars from 2011 to 2013, works on the 2014 Mustang GT produced after July 1 2013? Then a guy who had a late build 2014 said his engine was really a Second Gen Engine. He found that out when the engine had some big problems and needed to be pulled. Now the reissue red key for the Boss engine is now semi-self installed. You get a Procal device tied to your VIN from Ford Racing. You load that program yourself. Then you go to the dealer to get your red key setup. It's the same for the Track Cal on the standard 2014 GT. You load that program yourself. It takes 20 minutes to load. Then it says if you want your old stock program back, it only takes 1 minute to load. I would take that to mean both programs are now on you ECU but you do not get a Red Key but rather use the Procal device.
