ROUSH Performance Pacs Boost 2015-2017 Mustang Power Ratings

An increase in horsepower and torque is within reach for 2015-2017 Ford Mustang owners, thanks to Level 1 and Level 2 Performance Pacs from ROUSH Performance.

ROUSH calibration engineers retain extensive OEM calibration experience, ensuring that the calibration included in ROUSH Performance Pacs offers strong performance without sacrificing drivability. Hundreds of hours spent in the lab and on the dyno, testing and validating, set our Performance Pac calibrations apart from guesswork tuning.

In addition to improved horsepower and torque, improved throttle mapping provides amazing drivability improvements throughout the power band.

ROUSH Performance Pac calibrations are programmed easily into the factory ECU via industry standard J2534 re-flash interfaces with our free Roush Diagnostic Tool (RDT) utility.

The “dongle” that is included in Performance Pacs for 2.3L EcoBoost and 5.0L V8 Mustangs allow the user to easily “flash” the vehicle's PCM at home, avoiding a visit to a Ford dealership or other ROUSH dealer.

V6 vehicles can have the calibration upgrade completed at any authorized ROUSH Performance dealership in under an hour.

In addition to the ROUSH Diagnostic Tool flash software, each Level 1 and Level 2 Performance Pac includes a ROUSH Cold Air Kit. ROUSH Performance Cold Air Kits are the most highly-engineered in the industry, and are designed and tooled in computer-aided design (CAD) to maximize available under-hood space. Each kit is injection-molded from premium automotive-grade materials for durability, and features a high-flow, high-capacity, washable, and reusable performance air filter that does not require oiling. With a lower intake restriction over stock, drivers will never need to upgrade, regardless of planned future modifications.

Level 2 Performance Pacs build on the previous package to supply even greater torque and horsepower, with the addition of a Axle-Back Exhaust System. The system is constructed entirely from stainless steel 3-inch tubing, features ROUSH resonators designed to intensify sound characteristics while minimizing harshness, and is finished off by chrome-flashed dual-wall tips.
