The Shoemaker Performance 2011-2014 Mustang GT Tune brings factory-level precision tuning to your modern N/A or forced induction Mustang GT. With custom-mapped calibration options from Rob “The Tunemaker” Shoemaker, these tunes unlock optimized throttle response, enhanced power delivery, and improved transmission behavior tailored to your setup.
With three calibration stages, you can get the right customization for your build. —Stage 1 is designed for stock or basic bolt-on builds using 91–93 octane pump gas; Stage 2 adds support for ethanol blends like E85 and upgraded intake systems; and Stage 3 is built for aggressive setups, including camshafts and high-octane or race fuel use.
