Does anyone know what the differences are between the FR1 tune and the tune ford used on the 09 Bullitt / 2010 Mustang GT? I know the 2010 GT tune is smart enough to compensate for the octane in the fuel so you can use either 87 or 93 and not damage anything.. I was wondering if there is a tune available to down load on my 07 to run the same tune as the 2009 Bullitt available yet ?
