Livernois Motorsports MyCalibrator Tuner

Elite Supercharged Performance Optimization. The Livernois Motorsports MyCalibrator Tuner is a high-performance calibration tool specifically engineered to harness the untapped potential of the 2007-2009 Mustang GT500’s 5.4L supercharged V8. By recalibrating the factory ECU, this tuner significantly increases boost efficiency, optimizes ignition timing, and refines air-fuel ratios. With a 93-octane performance tune, owners can see peak-to-peak gains of over 45 wheel horsepower and 48 wheel torque, transforming the original GT500 into a much more aggressive and capable machine.

Tailored Calibrations for Boosted Applications. Unlike generic tuners, Livernois Motorsports leverages decades of racing heritage to provide custom-developed tunes that account for the unique thermal and mechanical demands of the early S197 GT500. Whether your 2007-2009 Shelby is stock or equipped with a smaller supercharger pulley and cold air intake, the MyCalibrator delivers a precision-mapped file. This ensures that the increased power is delivered safely, protecting your engine's internals while maximizing the volumetric efficiency of the factory Roots-style supercharger.
