5.4L Boss

STAGE 1 – +20RWKW

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

STAGE 2 – +40RWKW

Our stage 2 Boss package includes the cold air intake from stage 1 and adds extractors which replace the restrictive factory exhaust manifolds. This vastly increases the breathing characteristics of the engine meaning larger power gains and response are possible. We add a twin 3” cat-back exhaust to give your car the v8 growl that it needs!

  • PR spec intake kit
  • PR spec ceramic coated headers and high flow cats
  • PR spec dual 3” cat-back exhaust
  • Full custom PR tune, including re-calibration of your engine and transmission computers
  • Before and after dyno runs
