The JLT 123MM Cold Air Intake package is a great first step modification for your GT500.

If you have a stock Shelby and are looking for more power this is the best place to start. This package offers great bang for your buck. The power package will raise boost 3-4 PSI and add up to 100-130rwhp on your shelby! Flywheel HP from stock of 500HP to 625-650HP! We also offer free tune updates for any future modifications purchased from VMP.

Package includes:

  • SCT X4 Tuning Device
  • JLT 123MM Cold Air Intake
  • 2.50" Supercharger Pulley 
  • 90MM Idler pulley
  • VMP Custom Tunes
    * RECOMMENDED: NGK TR7-IX Spark Plugs gapped to .026 - .028" *

We only use the highest quality parts in our packages. Each custom tune is written by a VMP tuning team member and our pulleys are designed to fit perfectly the first time.

The Intake and Tune alone result in a 60-80RWHP and 60-80RWTQ gain on 07-09 and 30-50RWHP and 30-50RWTQ on 10+. In conjunction with the smaller pulley total gains will be 100-130RWHP and 100-130RWTQ on 07-09 and 50-70RWHP and 50-70RWTQ on 10+ (measured at wheels). Most cars will dyno 525-550RWHP depending on weather conditions with intake, pulley, and tune installed. 10+ start off higher due to the more aggressive factory calibration and factory intake, but end up in a similar place as 07-09 once these modifications are performed. The pulley may be installed at a later time, the tune will automatically adjust for it. Up to 3 custom tunes can be loaded onto your tuner, select 93-92, 91, race fuel, or Torco octane booster tune.

If you have any other mods note them at the time of ordering so they can be taken into account, such as long-tube headers or different rear end gears.

If you have special octane requirements let us know and we can create a tune for you. We have shipped our tunes all over the world and are familiar with the fuels available in Europe and other regions such as 95 and 98 RON.

The SCT X4 flash tuner is warranty friendly. The flasher saves your stock tune the first time you use it. You are able to flash the vehicle back to stock at any time. There is no way for the dealer to know that the vehicle was flashed.

Each SCT Flasher comes loaded with user adjustable options. You are able to change parameters such as tire size and rear end gear ratio yourself.

The flasher is fully re-programmable, new tunes can be emailed as you modify the vehicle.

*We highly recommend the use of the VMP Ultimate Pulley Removal and Installation tool. It is a specialized tool made specifically for this job, most Ford dealers and mechanics will not normally have such a tool. They may have other tools that will work, but the time spent and the damage caused is often not worth the trouble. Our tool is designed to take the stock pulley off without damaging it, and allows for easy installation of the new pulley. Our installation tool uses a large bearing to allow the new pulley to be installed on center and with relative ease (due to lack of friction). No heat is required when using our tool. We can not guarantee the installation of our pulley when other tools are used.

*There are absolutely no refunds on custom tuning*

Tuning labor is not refundable - modified vehicles can be highly variable and could have different issues that may be difficult to diagnose over the internet. We are happy to work with you to solve any issues with your vehicle but you must be able to datalog if necessary - all datalogging support is handled via email.
