Ford Performance Power Pack Calibration K Mustang GT 2018-2020 FRDM9603-M8B

The Ford Performance Power Pack Calibration K transforms your 2018-2020 Mustang GT from a capable performance car into a genuinely potent machine. With 42 lb-ft of additional torque available at just 2,000 rpm, you'll feel the difference immediately off the line and throughout the power band. This is a bolt-on upgrade that delivers measurable gains without compromising reliability or emissions compliance.

The kit combines three essential components—a high-flow cold air intake, an 87mm throttle body, and Ford's ProCal 4 calibration tool—to optimize your engine's breathing and fuel mapping simultaneously. Rather than chasing marginal gains with a single modification, you're getting a cohesive system engineered by Ford Performance to work in harmony. Installation is straightforward for experienced DIY enthusiasts, though Ford recommends professional installation through a dealer or ASE-certified technician to preserve your 3-year warranty.
