Boost Your Mustang’s Performance. With the Roush Performance Pac with Dongle (Level 2), your GT Mustang will receive a boost in horsepower, torque, throttle mapping, and boost. The Pac includes the Roush Performance Cold Air Intake, the Roush Axle-Back Round Tip Exhaust System, and a Roush-designed re-calibration for your car’s PCM. Everything you’ll need to take command of the high-performance Mustang scene is included in the Performance Pac.

Quality You Can Trust. Like all Roush parts, the Performance Pac has excellent quality that makes it a smart investment for any muscle car owner. Materials like 304 stainless steel guarantee durability, while CAD-designed structures ensure a perfect fit.

Roush Re-Calibration. With the Performance Pac, Roush has included a dongle to “flash” your PCM right from the comfort of your own garage. The free RDT software requires only a standard J2534 tool to easily reprogram the specific calibration into the ECU. Finishing the job of installing the Power Pac won’t require you to make a trip to the dealership and hand over your keys, and you’ll take less time to get back out on the road.

Three-Year Warranty. Roush backs their Performance Pack with a three-year/36,000-mile limited warranty. Please see manufacturer warranty for details and exclusions.

Application. The Roush Performance Pac with Dongle (Level 2) is designed to fit all 2015-2017 Ford GT Mustangs.
