5 STAR TUNING
Let our valuable customers do the talking..Frequently asked questions
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 it 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, increase 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 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 vehicles 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 the 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 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. For more information on what qualifies for free tune upgrades visit https://5startuning.com/free-tunes-life/.
Want More Performance? A 5 Star Tuning Custom will dramatically improve your drivability, horsepower, torque, throttle response, efficiency, and towing capacity. Eliminate your factory speed limiter, sluggish throttle, sloppy shifts and lackadaisical nature of your vehicle.
How Do We Get More Performance? Our tunes bring the most potential out of your vehicle by adjusting your fuel tables, drive by wire, timing, torque converter, shift strategies and shift pressures. Visit our Custom Tuning Info section for more detailed information for your specific vehicle.
What Can My Device Do? For starters, your device is extremely versatile. In addition to being your flash programmer it can perform many other functions. It can easily load store up to 10 of your 5 Star Tuning custom tunes. Your device can also be used to monitor your vehicle engine parameters. (Parameters can range from engine RPM, Speed, Coolant Temperatures and many more). The tuner can also be used to datalog your vehicle to further dial in current or future modifications. Your flash programmer will also store a copy of your factory tune and your vehicle can be returned to stock at anytime.
Which Tunes Are Available For My Application? Our entire lineup of tunes for your vehicle can be found by visiting our calibration request form. All of our current tunes for each application can be found under our custom tune dropdown menu.

I finally took the plunge and bought a 5 Star Tune for our 2014 Jayco Precept with the F-53 chassis. The first thing I noticed right off the bat was the immediate and snappy throttle response – instant smile :).
But wait, it gets better – the shifting, OMG the shifting! Gone are the short shifts, drawn out shifts, sudden slams into a lower gear and engine screaming, unpredictable torque converter locking/unlocking, etc.
Between the increased horsepower, torque and trans programming 5 Star Tuning has hit the ball out of the park in my opinion. My 11-year-old Class A is a whole new vehicle and the spark is back in the relationship.
Don’t wait as long as I did (40,000 miles), this unit is well worth the $’s and even though my MPG’s weren’t really affected my SPM (smiles per mile) has increased dramatically!
What a difference. Installed to our 2020 FR Georgetown and it made an instant difference. Super easy install shift points much better, no high RPM rev, engine noise decreased. Held off for some time due to price point. Silly me
I have had mine in my 2016 Holiday Rambler Vacationer with the Ford V10………..The tune is awesome! Like a totally new engine under the hood with this tune. Easy to install. Highly recommended.
My previous class A was an older 32 with a Chev V8 fitted with the full Banks Power package. I was always impressed with the power on this rig. Recently purchased a newer 33 Itasca Class A with the Ford V10 and was really disappointed with the power and acceleration. I was considering the Banks package and Five Star recommended the tuner.
Purchased and installed it just prior to our annual trip south. I am blown away with the difference in power and acceleration. Hill climbing towing a flatdeck with two ATVs is a breeze. The engine braking shift points are improved and really effective. The Itasca is a heavier higher rig and I believe it performs better than my previous rig with the Banks package with the Five Star Tuner!
In short it feels like someone dropped a bigger better engine in when we weren’t looking. After 5000 miles testing I am really pleased with the results. Gas mileage did not seem to be affected either way. Unbeatable “bang for the buck”

I have had this tune on my F53 V-10 RV for 2 years now, what a difference from the stock tune. More power, acceleration, and hill climbing ability. Smoother shifting without the low gear ‘roar’ you get, so better shift points. Did not seem to affect my MPG at all. I have about 20K miles on it and could not be happier. Great job 5Star!!
