    2015-19 Mustang 3.7 TUNE DESCRIPTIONS

  • 93/91/87-89/E30 PR-X Performance Tune:
    PR-X, also known as Performance Race Xtreme, is our top-performance tune for the 2015-19 Mustang with a dyno proven gain of 35 HP and 34 ft-lbs of Torque on the 3.7L. Due to the impressive power gains and performance mannered driving, this is by far the preferred tune for the 15-19 Mustang. The Mustang feels so much lighter with the increased throttle response and part throttle power. Wide open throttle power is noticeably increased as well and can be as much as 40 HP depending on the rpm. The stock calibration has several dead spots where the car just doesn't feel sporty. This feeling is resolved with the MPT custom tune. With this tune you are looking at huge increases in low end torque and acceleration, faster 0-60 times, quicker 1/4 mile results and shift points optimized with a focus on performance. The shift points will still be fuel efficient at very low throttle positions but will happen at a higher rpm/mph when throttle position is increased. The shifts will also be firmer and more crisp than stock. Sport mode has a noticeable increase in throttle response above that of the already increased base shift mode. We also modified sport mode to make the minimum rpm to shift lower. This lets you drive in sport mode more comfortably and click back into regular drive when you want to be more economy minded. This tune applies to both Auto and Manual transmissions.

  • 93/91/87-89/E30 PR-X Performance Tune - No Trans Tuning:
    This tune has all the benefits of the above PR-X but has the trans setup very mild for those that prefer the stock feeling shifts of the car.

  • Any Octane Performance Trans Only:
    This tune can be used with any octane fuel, the concept behind this tune is to take the improved shifting and performance of the PR-X tune but leave spark, fuel and other items stock. Throttle response and part throttle acceleration will still have a noticeable increase over stock.

  • 93/91/87-89/E30 Perf-Econ:
    The Perf-Econ tune, also known as Performance Economy Hybrid is a perfect blend of low end fuel economy and top end power. This tune keeps the closed pedal and very low throttle positions controlled to make sure fuel economy is optimized. Shift points at lower throttle positions will be slightly sooner than stock to get you into higher gears faster. Then it also has improvements on power and throttle response at higher pedal positions. Great tune for those that want the option for power but don't want it full time.


  • Octane: Gas vehicle tunes are heavily impacted by the octane of fuel being used. Running a higher octane allows us to advance the spark more which results in better performance. That being said, you should pick tunes for the octane you plan on running. If you always have and always will run 87-89 octane, then that is what you should choose. You can run a tune for 87-89 octane and fill the tank with 93, however you cannot run a tune for 93 octane and fill up with 87-89. Doing so will result in knock activity, a loss of power output and in rare cases, possible engine damage. Our recommendation for performance tunes is to run the highest octane available.

    If you desire the max performance and have access to E85, then we recommend making one of your tunes E30. This is done by mixing 91 or 93 octane fuel with E85. There are several online calculators you can use to determine the correct mixture. Please note, if you have an E30 tune you must have an E30 mix in the tank. If you do not plan on running E30 full time, then make sure you have an alternate tune you can load when needed.


  • Speed Limiter: Speed limit can be set lower, higher or turned off on each tune. (Valet or teenager specific tunes.)
  • Aftermarket Cold Air Intake: If aftermarket, enter brand and model of the CAI.
  • Aftermarket Throttle Body: If the car has an aftermarket throttle body, indicate the details on the form.
  • Aftermarket Intake Manifold: If the car has an aftermarket intake manifold or ported intake manifold indicate the details on the form.
  • Thermostat: If you have an aftermarket thermostat, enter it here and your fans will be updated.
