The M-9603-M8B Mustang GT calibration for 2018-2021 5.0L equipped Mustangs is a blast to drive. Like other Ford Performance calibrations it features improved power throughout the RPM range. The throttle really comes alive. This package was modeled after our very successful M8A Power Pack 2 for 2015-2017 Mustang GTs. It features a larger 87mm throttle body (vs. 80mm stock), the required throttle body adaptor, a Ford Performance cold air intake, and the Pro Cal 4 tool. It is available for manual or automatic equipped Mustang GTs.
Do Ford Performance calibrations have a warranty?
Ford Performance calibrations are unique because they come with their own Ford warranty. If the Ford Performance calibration causes an issue to your car within 3 years or 36,000 miles from new vehicle in-service, Ford pays to fix your car. If the performance calibration did not cause the issue, your base Ford warranty still applies. The kits need to be installed by an A.S.E. certified shop or Ford dealer.
What about competitors' calibrations?
Ford does not and cannot warranty non-Ford calibrations. Ford does not develop or test them and therefore will not cover any affected parts damaged by a non-Ford calibration. They do not test and develop to Ford's durability standards.
