ProCal 4 Calibration Kit

The Ford Performance M-9603-M4CA calibration kit is engineered to unlock significant performance gains for your Mustang EcoBoost. This system delivers a peak increase of 35 horsepower at 2,900 RPM and 76 lb.-ft. of torque at 2,600 RPM, providing a noticeable boost throughout the powerband. Included in this comprehensive package is the ProCal 4 calibration delivery tool, a Ford Performance High Flow Performance Air Filter (M-9601-M), and a calibration voucher. It also comes with an exclusive Ford Racing Parts warranty when installed by a dealer, offering peace of mind. This calibration is street legal in all 50 states with a CARB EO (D-431-6). It fits 2018-2023 Mustang EcoBoost models equipped with either manual or automatic transmissions. However, it is explicitly noted that this calibration is not for use with the 2020-2023 2.3 HO engines. The calibration voucher provides instructions, and for any questions or concerns, the Ford Performance Tech Line is available for assistance. Note that if a stock calibration re-installation is necessary due to PCM limitations, a Ford dealer visit is required for 'as-built' calibration installation.
