5.4L Boss


Our stage 1 Boss package touches on the few things that we believe could have been addressed better from factory, obviously they weren’t due to budget constraints or similar. We fit our PR spec cold air intake, as well as a PR custom tune which refines and improves your throttle response, shift feel and overall feel of the vehicle. As always our packages make your cars performance repeatable and consistent!

  • PR Spec Intake Kit
  • Full custom PR tune, including re-calibration of your engine and transmission computers
  • Before and after dyno runs
