X900S Shelby GT500 Packages

The 2020+ Shelby GT500 is not only the most capable Mustang ever released from the factory but it can also make far more power than a typical 5.0/5.2L on 91/93 Octane! Palm Beach Dyno bought a car specifically to develop these packages to ensure a trouble free experience while modifying your GT500. Available in 3 different levels, they are intended to be a mapped out upgrade path and put in a particular order to ensure you don't have to do double work or buy the same part twice as you upgrade.
