Do you have a 2015+ Mustang with the I4 2.3L EcoBoost engine and want some more power without spending a fortune? You’re in luck!
The Roush Performance Flash Pack for the 2015+ 2.3L I4 EcoBoost Mustangs adds an exceptional 42 RWHP and 35 lb-ft. of torque to the stock 2.3L Ecoboost engine. As if that wasn’t enough, an optional 3-year/36,000-mile ROUSH Limited Powertrain Warranty gives you confidence to crank up the power!
Roush calibration engineers have extensive OEM calibration experience and sweat the details to ensure strong performance without sacrificing drivability. Hundreds of hours spent in the lab and on the dyno, testing and validating rigorously, set our ROUSH calibrations apart from “guesswork” tuning found in other kits.
In addition to improved horsepower and torque, our kit also provides improved boost and throttle mapping that will lend a “sportier” feel right off idle to provide amazing drivability improvements all through the power band.
Do you have the ROUSH 2015+ I4 2.3L Mustang Cold Air Intake installed, but want even more power? Adding this Flash Pack to your existing setup will get you the equivalent of our “Level 1” Power Pack System (51 RWHP/45 RWTQ)!
Do you have the ROUSH 2015+ I4 2.3L Mustang Cold Air Intake & ROUSH 2015+ I4 2.3L Mustang Axle-Back Exhaust installed, and want the most power possible out of your stock 2.3L I4? Adding this Flash Pack to your existing setup will get you the equivalent of our “Level 2” Power Pack System (60 RWHP/51 RWTQ)!
The ROUSH calibration in our Power Packs is easily programmed into the ECU of the vehicle via an industry standard J2534 tool & our free Roush Diagnostic Tool (RDT) software (note: dealer service charges may apply). Most dealers, should they be equipped with the proper tool, can complete the calibration process in under an hour. Our extensive list of ROUSH Performance authorized dealers can be found at the top of our web page.
