Edelbrock E-Force Stage 1 Street Supercharger System (TVS R2650), w/ PCM Unlock/Tune

A supercharger kit for the 5.3L. A belt driven roots style blower takes the place of the factory intake manifold and forces more air into the engine than it can draw on its own. This version ships with the PCM unlock and calibration included.

why this one — It is the most expensive kit in this group, but it is the only one that arrives with the ECU unlock and tune in the box, so there is no separate trip to a dyno tuner before you can drive it. Edelbrock claims 485 horsepower and 466 lb-ft at the rear wheels on 93 octane with the supplied calibration and the 4.00 inch pulley. Fitment stops at 2021, so 2022 and newer trucks need a different kit.
