Mustang Dark Horse SC & GTD Tune Package

Take your Mustang Dark Horse SC or GTD to the next level with a custom Shoemaker Performance calibration built specifically around your vehicle, modifications, fuel, and performance goals.

From basic bolt-ons to extensively modified combinations, we offer two tuning levels to match your build.

Level 1 — Stock / Basic Bolt-On

Level 1 is designed for Dark Horse SC and GTD Mustangs with stock or basic bolt-on combinations.

This level covers straightforward setups with common modifications such as cold air intakes, exhaust upgrades, and other supported bolt-ons.

Your calibration is custom developed around your specific combination to optimize power delivery, throttle response, and drivability.

Level 2 — Advanced / High-Horsepower

Level 2 is intended for combinations requiring more extensive calibration work, including upgraded fueling, alternative fuels, increased boost, supercharger upgrades, built engines, and other significant performance modifications.

This level provides the additional calibration development and revisions needed to dial in your combination. Fuel and modification compatibility should be confirmed with Shoemaker Performance before ordering.
