The ROUSH M90 Mustang supercharger system has been extensively design, used, and proven as a rock-solid piece. Part of the robustness comes from a hidden but very important part of the system: the ROUSH calibration.

ROUSH is widely recognized as a market leader for calibration in the automotive world. It's because of this expertise that our systems not only perform, but they also make your engine last. A common problem with calibrations from our competition is that they destroy the engine or cause poor drivability with incomplete calibrations across the environmental extremes. You will not find these problems here. As a result, we stand behind this Mustang supercharger kit with an industry-leading 3 year / 36,000 mile drivetrain warranty or one year on ROUSH components for vehicles past their warranty expiration (see the ROUSH warranty document for details). Once you receive your M90 2009 Ford Mustang Supercharger, simply send us your PCM (shipment fee for PCM is included in purchase price). We will then update the PCM and send it back to you.
