Why Tune My Vehicle? From the factory your vehicle’s computer is calibrated for the masses, designed with the average driver in mind, not the performance enthusiast. This not only leaves valuable horsepower & torque hidden inside your vehicle, but is also makes for a mediocre driving experience. Our tuners unlock your vehicle’s hidden performance by re-calibrating your vehicle’s PCM for maximum horsepower & torque, increased throttle response, clean shift points, increased efficiency and the best driving experience possible.

Why 5 Star Tuning? We are your industry leader in Ford and GM truck, car, suv and motorhome tuning. We create and offer the most refined tunes on the market for your application. Rather than offering you a one-sized fits all approach we custom tailor all of your tunes to your specific needs. These needs can be more power, more torque, tuning for your current or future modifications or simply getting the best driving experience from your vehicle. In addition to our refined approach to tuning vehicle, we ensure your vehicle’s reliability will never be compromised.

Dyno & Street Proven Tunes! Our 5 Star Tuning custom tunes have been dyno developed, refined, tested repeatedly, street tested, tow tested and driven all over the country in our own personal vehicles. Nothing says highest quality tune on the market such as investing in our own vehicles and testing them for over a million test miles by our own engineers.

Free Tunes for Life! Have you added a new mod to your truck, car, suv or motorhome and wish to maximize your application’s performance? For all of our Tunes for Life members these modifications are free for the life of your vehicle while you own it. This will ensure that your vehicle run properly with our dyno and street tested tunes give you the most horsepower, torque and most efficient performance possible with your newest addition.

Want More Performance? A 5 Star Tuning Custom will dramatically improve your drivablity, horsepower, torque, throttle response, efficiency, and towing capacity. Eliminate your factory speed limiter, sluggish throttle, sloppy shifts and lackadaisical nature of your vehicle.

Which Tunes Are Available For My Application? Our 87 Performance/Tow VCT tune is the perfect fit immediate tuning of your stock vehicle with VCT blocks. Other tune options are available for higher octane as well as for those applications that feature other modifications.

About The Kit:The Freedom Racing VCT kit is the perfect solution for your 4.6L or 5.4L 3V F-Series or E-Series vehicle. Eradicate excessive motion and cam chatter & prevent downtime due to costly repairs.

  • ST-100 3V Timing Chain Locking Wedge – 303-1175 Alt

This tuner comes pre-loaded with a 5 Star Tuning custom tune file for your vehicle and instructions.

Do not run your vehicle with the locked out phasers until you install your free tune file. There are no returns allowed on this kit.

Before installing locked out phasers you should first make sure that your ECU strategy code is recognized by the tuner device. If you see an “Unsupported Vehicle” message follow the steps in the included instructions to request a custom tune file from 5Star Tuning. It may take a few business days for 5Star Tuning to build your custom tune, so you may not want to begin the job yet. If your ECU is recognized and the new tune is loaded, you can always return the vehicle to the stock tune if you aren’t ready to begin the job.
