Mustang Mach-1 Makes 540HP With Stage-2 NA Package!

The S550 Ford Mustang Mach-1 is a seriously fun driver's car right off the showroom floor! And for the Mach-1 owner who wants more without upsetting the incredibly balanced factory performance, our Stage-2 Naturally Aspirated package is the way to go! More usable horsepower & torque across the powerband, more of the great sounds you want, all without impacting drivability, reliability, or fuel economy.

In this video, we give you a look Over Our Shoulder as we install our Stage-2 Naturally Aspirated package, with additional Steeda K-member and Ultimate Stop the Hop suspension, topped off with the optional Inferred Flex Fuel calibration, and show you the real-world results back-to-back on the dyno.
