Adds 29 hp and 36 lb-ft to the rear wheels

The ROUSH Level 2 Performance Pac for the 2015-2017 Mustang GT Coyote 5.0L V8, adds an exceptional 29 RWHP and 36 lb-ft. of torque to your stock Mustang GT V8. An optional 3-year/36,000-mile limited powertrain warranty gives you confidence to crank up the power.

The included ROUSH cold air kit is fully tested and calibration certified to work seemlessly with our performance ECU re flash and adds a sporty sound to the 5.0L Coyote V8 engine. Our cold air kits are the best in the industry, designed and tooled in CAD to maximize available underhood space, and injection molded from premium automotive-grade materials for long life. A lower intake restriction over stock, ensures you will never need to upgrade your intake.

The ROUSH premium 2.5" axle back exhaust system is built from high quality 304 grade stainless steel for long life and great sound. The system includes all hardware, and is fully tested to work as a system with the ROUSH cold air kit and ECU flash.

Roush calibration engineers have extensive OEM calibration experience and sweat the details to ensure strong performance without sacrificing driveability. Hundreds of hours spent in the lab and on the dyno, testing and validating our calibrations, set our Performance Pacs apart from guesswork tuning.

In addition to improved horsepower and torque, more aggressive throttle mapping provides a sporty feel throughout the entire power band. ROUSH Performance Pac calibrations are uploaded easily into the factory ECU via industry standard J2534 refl ash interfaces, with our free ROUSH Diagnostic Tool, (RDT).

Included dongle allows for the ability to easily “flash” the vehicle's PCM at home, avoiding a visit to a Ford dealership or other ROUSH dealer.

Experienced DIY'ers and nearly any dealer can perform the calibration upgrade in under an hour without getting their hands dirty.
