I bought a Super Charger for my fully loaded 2013 GT. When I got it, It said, "It was not reccomended for an auto-trans". I should have paid less and had a better Trans. I paid a 15% re-stocking fee.(Super Chargers aren't cheap)
I also bought a BBK 90MM Throttle body which is worthless to me without an forced air induction. I ended up putting a Airaid CAI with a Bama tune on the chip, a 85 mm BBK throttle body and SLP Cat back Pipes. I have done work for DR. Gas for the last 14 years, He owes me some X-pipes. My GT runs like a "Raped Ape".
The Factory Warranty was voided 7 days after purchase, I wanted a GT capable of taking any Cobra. My dream was crushed because of a Tranny.
I did not re-stock the Throttle Body and its for sell. It will fit any GT or Cobra 2011-2013. I'm willing to take a $150.00 loss. It will add 20 HP to a forced air induction. $400.00 and its yours. (I'll pay shipping)
Another shameless plug for my mistakes.



LOL, my mistake could be your gain!
BTW, I'll put this stang back to stock if I have to deal with the warranty.
LOL, 7 months, 4,000 miles. I don't have to worry.
