Increase Horsepower and Torque. The 3.5L EcoBoost F-150 rolled off the assembly line with an impressive 365 HP and 420 ft-lb of TQ, however if you feel that power is just not enough, then it's time to start adding some aftermarket performance mods. However, some mods need a little help in the form of a custom tune. That is where MPT Performance comes in. By adjusting the ignition time, tweaking the variable cam timing and optimizing the air/fuel ratio, a custom written MPT Tune will squeeze out the extra power your modifications have to offer.

MPT Performance Custom Tunes. When you order a set of three custom tunes from MPT Performance they are written specifically for your personal 3.5L EcoBoost F-150 and your particular modifications with your choice of octane level. MPT Performance even provides one post sale datalog review (if necessary) to assure your truck is running healthy and strong. MPT offers six different tunes that you can choose from which includes the PR-X High Boost Tune, PR-X High Boost Tune – Stock Trans, Performance Tow Tune, Performance Tow Tune – Stock Trans, Perf-Econ Tune and Performance Trans Only Tune.

PR-X High Boost Tune. This PR-X Tune, also known as the Performance Race Xtreme, is MPT's top performance tune that provides the most gains in power and performance. Available for 91 or 93 octane fuel only, this tune will make your F-150 feel lighter due to the increase in throttle response and part throttle boost. When compared to stock, the wide open throttle boost is increased by +/- 15%, which translates to 3/5 PSI (depending on the RPM). With a peak boost around 19 PSI +/-, this PR-X tune provides an increase in low-end torque and acceleration, which translates to quicker 0-60 and 1/4 mile times. When compared to the factory tune, the PR-X Tune makes your shift points much firmer at higher RPMs and MPH. Your factory Sport Mode will also experience a noticeable increase in throttle response, when compared to the base shift mode. MPT also has an E30 version of this tune that is designed to be used with a mixture of E85 and premium fuel.

PR-X High Boost Tune – Stock Trans. If you prefer the factory shift points of your F-150, then this tune may be for you. This tune features the same benefits as PR-X Tune, but MPT makes sure the transmission setup is very mild for the F-150 owners that like the feeling of the stock shifts. This tune only can be used with 91 or 93 octane fuel.

Performance Tow Tune. Sometimes referred as a "Street" or "Daily Driver" Tune, this tune is a step under the PR-X Tune and can be used with 87-89, 91 or 93 octane fuel. MPT designed this tune to be a towing and performance tune hybrid with a peak boost around 15 PSI +/-. The throttle response and part throttle boost is improved drastically when compared to the stock tune, but it's not as aggressive as the PR-X tune. Even though this tune has a focus on performance, you'll still be able to use this tune when you need to tow or haul.

Performance Tow Tune - Stock Trans. If you prefer the factory shift points of your F-150, then this tune may be for you. This tune features the same benefits as Performance Tow Tune, but MPT makes sure the transmission setup is very mild for the F-150 owners that like the feeling of the stock shifts.

Perf-Econ Tune. Also known as the Performance Economy Hybrid Tune, MPT created this tune to provide a perfect blend between low fuel economy and top-end power. Designed for the F-150 owner that want power but don't want it constantly, this tune controls the closed pedal and very low throttle positions to ensure your fuel economy is enhanced. The tune can be used with 87-89, 91 or 93 octane fuel.

Performance Trans Only Tune. Designed to be used with any octane fuel, this tune gives you the improvement in shifting and performance of the PR-X tune but leaves the fuel, spark and other features at the stock settings. MPT made sure you would have a noticeable increase in throttle response and acceleration with this tune when compared to the stock tune.

Compact Design. The SF4/X4 Power Flash Tuner measures in at 2.7” wide X 5.5” tall making it much smaller than the original SF3/X3 for easy storage in your center console or glove box. The cord is detachable and there is no battery or power supply needed. It uses the power from your vehicle's diagnostic port or computers USB connection.

Full Color Display. The SF4/X4 Power Flash Tuner features a full color 2-3/4" diagonal LCD screen with user adjustable portrait or landscape modes. The SF4/X4 also has a convenient power saving auto dim feature.

Built-in WiFi. The SF4/X4 Power Flash Tuner is now WiFi-capable meaning you will no longer have to plug it into your PC/Windows computer to receive the latest SCT firmware updates.

Diagnostics. The SF4/X4 Power Flash Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own trouble codes rather than paying a dealer to do the same. Its as easy as a few simple steps.

On Screen Data Logging and Monitoring. With a full color LCD display, the SCT SF4/X4 Power Flash Tuner makes it EASY to read the Built-In Data Logging or Real Time Monitored Vehicle Data, view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source.

Easy to Load; Easy to Restore. When you load a custom tune on your F-150, the tuner automatically stores your vehicle's factory settings. To return the truck to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

Application. This SCT SF4/X4 Power Flash Tuner with a set of three MPT Performance Custom Tune Files is designed specifically for the 2015 to 2016 F-150s equipped with the 3.5L EcoBoost V6 Engine.
