Tech Tip: Horsepower and torque gains will not be optimized until fuel octane is learned. Peak gains are measured as the difference between the highest points of the two plots. Max gains are measured as the largest gain at any single point between the two plots, results may vary. Powertrain calibration is developed and supported for U.S. and Canadian vehicles ONLY--this calibration WILL NOT work on Non-North American Mustangs. Premium fuel, 91 octane or higher, is required.
