The only Mustang GT Performance tune on the market with true 87-93 octane support like the factory tune!
Send out a PSA that the roads are no longer safe because the Monster Tuned Power-X tune for the 24+ s650 Mustang GT will unleash the hidden potential of your already potent 5.0 V8 Coyote Engine. Once flashed you won't be able to keep your foot off the pedal and every red light will be a staging lane!
Our Power-X line of calibrations are an improved version of the OEM Ford calibration. We start from the OEM stock map then increase the vehicle's ability to quickly reach MBT timing as soon as possible creating a great overall power curve. After some final combustion optimization the result is a whopping 13-14 WHP Peak gain on an all STOCK Mustang GT.
Our tunes are designed to operate within acceptable knock thresholds that are used on the stock calibration and maintain all factory safety controls resulting in trusted long term reliability.
The Mustang GT Power-X calibration will support 87 through 93 octane like the stock calibration, however if you are not running 91 or higher you will see minimal power gains. We recommend using only premium fuel (91+ octane) for best performance in your Ford Mustang GT 5.0 Coyote Gen 4.
Power-X calibrations are specific to MAF based vehicles naturally aspirated platforms. The 24+ s650 Mustang GT uses a MAF sensor located near the airbox to measure airflow. This means that changing the intake will impact how the car reads airflow and can throw off fueling. Always ensure that your tune is correct for the airbox/intake that's being used. Additionally based on dyno testing done in-house we believe the stock airbox with a drop in knn/green filter is actually the most optimal solution for naturally aspirated vehicles.
All Power-X calibrations are emissions compliant and will pass emissions testing. Removing or tampering with emissions equipment on your vehicle will result in a check engine light and the vehicle failing an emissions test.
Upgrade to Power-X and unleash your vehicle’s full potential today.

What kind of power should I expect?
The power that you get will be heavily dependent on cooling and fuel quality. We highly recommend keeping the factory airbox (and with the oem lid) as it flows very well up to 600 HP while keeping temps very low, and provides a fresh air feed from the grill. After market intakes may see a reduction in power due to increased intake air temperatures.
Power figures are based on in-house dyno testing with our 2024 10R80 Mustang GT and quoted as crank horsepower numbers. Multiply numbers by 0.88 to get dyno figures.
- Stock: 486 HP
- 91 Fuel: 496 HP
- 93 Fuel: 502 HP
- E30 Fuel: 526 HP
*** Ethanol Mix Notes ***
When mixing always allow 15 miles of driving for the fuel to mix before going wide open throttle. Failure to allow the fuel to properly mix can result in excessive knock.
For E85 pumps that do not state an e70 minimum statement we recommend testing your fuel at least once a month using an ethanol test kit.
