Lethal Performance 2013-2014 GT500 Boost Upgrade Kit w/ SCT X4

*image is only a representation and may not be accurate

You can expect to gain anywhere from 85-95rwhp (based on 93 octane) and some customers have reported over 100rwhp gain with this package on a 93 octane tune.

Since the 2013-2014 GT500 comes already equipped with a high flow air intake system, we felt it necessary to put a kit together specifically for those looking to get the power of a pulley and tune without needing to purchase another air intake system.

Lethal Performance Custom Tuned Xcal 4 - With the addition of the supercharger pulley a custom is needeed. Lethal Performance offers the industries best high performance tuning. Each tune we send out was built from countless hours on the street and dyno evolving it into the best tune available for your vehicle.


The Lethal Performance Boost Kit includes

  • Billet Pro Shop 2.396" Stock Look Supercharger Pulley - Standard
  • Billet Pro Shop 90mm Idler Pulley - Standard
  • Ford Racing Dual 65mm Cobra Jet Throttle Body - Standard (Ford Racing SCJ Monoblade can be substituted for more power)
  • NGK BR7EF spark plugs (set of 8)
  • SCT X4 Programmer
  • Lund Racing Custom Tune

You can even add that extra PUNCH by adding our Lethal Performance Off Road mid pipes for a discounted price! If you wish to add the mid pipe to the order, just select it from the drop down menu above! We picked up 15rwhp on a stock car with the stock tune.

You can expect big gains with the addition of this package.

NOTE: Different dynos will give different numbers on different days. Numbers posted are experiences from Lethal Performance and it's customers. The race track tells the real story
