Packing 660+ horsepower at the flywheel, the 2013-2014 Shelby GT500 is fun to drive right from the factory. But, for some, 660+ flywheel horsepower just isn't enough. If you're looking to up the anti of your Trinity 5.8 L powered GT500, we put together a series of packages to give you the additional power you're craving! 

The VMP 2013-2014 GT500 Stage 4 Power Pack has everything it takes to deliver up to a 100+ rear wheel horsepower increase. 

VMP has extensive experience tuning a wide range of Ford vehicles. We apply our dyno-tuning experience to all our e-mail and mail order tunes. The benefits of a VMP custom tune includes, but isn't limited to (varies by application): 

  • Firmer and faster shifting for automatic trans vehicles, slightly firmer at part throttle, much firmer at WOT.
  • Removed speed limiter (do not exceed tire or driveshaft rating)
  • Safely raised rev limiter 200-400 RPM.
  • Advanced timing for improved response and power at all RPM ranges
  • Optimized air fuel ratio for more power at WOT
  • Permanently turn traction control off (specify when ordering)
  • Turn shift light off (specify when ordering)
  • Tow tunes that increase fuel economy and reduce trans temps while towing
  • Torque converter lockup at WOT for more power to the wheels
  • Optimized engine fan cooling on/off temperatures for less heat-soak
  • And much much more depending on the individual vehicle.
