I guess the Ford Racing Professional Calibration tune and auto trans are not a common modification.
On another note, I got the 2011-12 GT500 Ford mufflers installed today. They make wonderful music, the subdued rumble of power. The muted rolling thunder is there during acceleration, but at 80 mph you cannot hear the exhaust. The bigger exhaust tips look menacing. These mufflers are a masterpiece of engineering.
Anybody need a pair of OEM 2014 stainless GT mufflers? Low mileage, only 514. What's the best way to dispose of these? They won't be cheap to ship, the Fed EX package with the GT500 cans was 45 pounds.
