Is there any other car besides a mustang haha. Dang 12.9 is quick mine best is 13.8 it just has xpipe jba axle backs jlt cold air and a bama tune it has optional factory 3.55 and some crappy tires lol
All I have done is JLT cold air, Steeda underdrive pulleys, Pypes axle back, 3.90 gears, and solid lower control arms. It was also dyno tuned at Evolution Performance. I had drag radials on it for the 12.9 . The 2011 and newer 5.0's run 12.8 stock.
