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