Enhance the performance of your 2.7L engine in your 2021-2023 Bronco.

If you are looking for more power from your Bronco, the best place to start is with our 2021-2023 Ford Bronco performance calibration kit. This Ford Bronco calibration system was developed by Ford Performance to improve the performance of a stock engine, while meeting emissions requirements in all 50 states. It delivers power and torque over the stock tune, while improving drivability across the RPM range. It also includes transmission programming, changing the shift points to get the most from the increase in power. You can also change your tire size calibration.

The Ford Bronco Performance calibration kit comes with a Pro Cal 4 calibration delivery tool. When installed by a certified technician, it's covered by a three-year/36,000-mile warranty. Using the Pro Cal tool, you can switch between the performance and stock tunes as needed.

Ford Performance has a long history of offering performance engine calibrations. These calibrations offer an enhanced driving experience. They are developed by Ford Performance calibration engineers during countless hours of dyno testing and real-time "seat-of-the-pants" drive-ability evaluation. The resulting calibrations offer improved power, driveability, and pass Ford Performance's stringent durability tests. Performance calibrations are available for U.S. and Canadian vehicles. Premium fuel is required.

Is this calibration legal in California?

Yes , Ford Performance spends great deal of time, energy, and resources to certify our performance calibrations for emissions for all 50 states California included. Ford Performance tests and certifies our calibrations meet the proper C.A.R.B. standards.

Do the Ford Performance calibrations have a C.A.R.B. Executive Order (EO) number?


Do Ford Performance calibrations have a warranty?

Ford Performance calibrations are unique because they come with their own Ford warranty. If the Ford Performance calibration causes an issue to your car within 3 years or 36,000 miles from new vehicle in-service, Ford pays to fix your car. If the performance calibration did not cause the issue, your base Ford warranty still applies. The kits need to be installed by an A.S.E. certified shop or Ford dealer. In Canada, Red Seal certified technicians also can install Ford Performance calibrations to maintain warranty eligibility.

What about competitors' calibrations?

Ford does not and cannot warranty non-Ford calibrations. Ford does not develop or test them and therefore will not cover any affected parts damaged by a non-Ford calibration. They do not test and develop to Ford's durability standards.

Notice: Accessport flashers, optimized calibrations, optimized calibration service time, or any other electronic tuning device cannot be returned. No exceptions
