    Review & Install Video

    Greater Torque and Horsepower. Roush Performance Pac with Dongle comes with a highly developed PCM calibration to boost your GT’s horsepower and torque across the RPM range. Roush combined their pioneering high-flow cold air intake and Flash Pac custom tune into a single kit to boost your 5.0L engine’s performance and deliver a noticeable performance boost.

    Optimized Calibration. Roush develops its first-rate fuel calibrations under tested laboratory conditions to guarantee efficiency. Enhanced throttle mapping similarly gives your GT an incredibly aggressive feel. These calibrations are optimized to be compatible with 91 octane fuel and fuels with lower octane ratings and reduced performance output and power.

    Unique Cold Air Intake. Roush engineered the cold air intake that comes with its Performance Pac using CAD data. As a result, any restrictions are eliminated thus optimizing airflow. Automotive-grade materials are used to manufacture the cold air intake for durability. Roush similarly included a premium filter with two wire mesh layers. Since it is washable, you do not need to oil the filter. What’s more, the filter retains its original shape even when under high flow.

    Hassle-Free Installation. Roush Performance Pac with Dongle has a simple design which makes it easy to install. No extra modifications are needed, and the process takes approximately 1 hour.

    Warranty. An optional 36,000-mile/3-year limited powertrain warranty is provided for the entire kit.

    Application. Roush designed this Level 1 Performance Pac Kit to be used on all 2015-2017 Mustang GTs.

    2 Top Rated Questions

    Can this Roush Level 1 kit allow you to adjust the speedometer for tire diameter changes and rear end gear ratio changes the same as the Ford performace pack can?

    Why is info on features speaking about performance increase that boost your turbo charged engine's performance. I have GT not a 4 turbo?

    • We do apologize for the confusion. We may have had a site issue where it was stating information for an Ecoboost Mustang but the page is now updated to reflect the information for the GT Mustang.
