I read in your post that you have the 4.6, not the 5.4 that the GT500's are running. Did they register your Mustang as a GT500? You also wrote that your Mustang's 4.6 is hopped up as well. Can you give us more breakdown on what your car is running? I ask this only because I also have a Mustang GT running a Saleen 475 HP SuperCharger, 4:10 gears, 3" exhaust, GT500 Wheels and tire set, a 91 octane Brenspeed tune. My Mustang GT is Torch Red, and I had the original tape stripes taken off and had 10" White stripes painted on.
Did the Dealership modify your Mustang and make it a GT500, and displaying the Snake emblems? I live in Arizona and have seen one Mustang GT with the above modifications, but the has emblems and decals showing that it is a GT350, the car is a 2007.
Any help you can give me would be greatly appreciated,
