5 STAR TUNING
Let our valuable customers do the talking..Frequently asked questions
Why Tune My Vehicle?
Your vehicle’s factory settings are designed for the average driver, not the performance enthusiast. This means that while your car may run smoothly, it’s not tapping into its full potential. Valuable horsepower and torque are left untapped, and the overall driving experience may feel underwhelming. Our expert tuners unlock your vehicle’s hidden power by recalibrating the PCM, optimizing horsepower and torque, enhancing throttle response, refining shift points, improving efficiency, and ultimately delivering a superior driving experience.
Why 5 Star Tuning?
As the leader in Ford and GM truck, car, SUV, and motorhome tuning, we offer the most advanced, customized tunes available. Rather than a one-size-fits-all approach, we tailor each tune specifically to your needs. Whether you’re seeking more power, increased torque, tuning for current or future modifications, or simply want the best possible driving experience, we provide a solution that fits. Plus, we prioritize your vehicle’s reliability, ensuring that performance improvements don’t compromise its longevity.
Dyno & Street Proven Tunes!
Our custom tunes are developed on the dyno, carefully refined, and rigorously tested. From street testing to tow testing, we’ve driven our tunes across the country in our personal vehicles, accumulating over a million miles of real-world data. Our commitment to quality is evident in how we test and refine our tunes, ensuring they’re the highest quality on the market.
Free Tunes for Life!
If you’ve added a new modification to your vehicle and want to ensure maximum performance, our Tunes for Life membership has you covered. As a member, any new modifications you make are eligible for free tuning for the life of your vehicle, ensuring your vehicle runs at its best with our dyno and street-tested tunes.

Want More Performance?

From improved drivability, horsepower, torque, and throttle response, to better fuel efficiency and towing capacity, our tunes give you a noticeable performance boost. Say goodbye to factory speed limits, sluggish throttle, and poor shifts. Experience the full potential of your vehicle.
How Do We Achieve More Performance?
Our tunes maximize your vehicle’s performance by fine-tuning key parameters such as fuel tables, drive-by-wire settings, timing, torque converter operation, shift strategies, and shift pressures. Visit our Custom Tuning Info section for specific details on how our tunes can benefit your vehicle.
