This is a Whipple Intercooled Supercharger System with the all new Gen 5 3.0L twin screw blower setup for the 2020-2022 GM/GMC/Chevy 6.6L 2500 & 3500 Trucks which will get you 700 ft-lb of torque on 93-octane fuel with only 7-8 psi of boost! This is the competition tuner kit which will require a custom tune done locally after you install the kit, and does not include a programmer or tuning. Programming and PCM unlocking available. Satin black finish is standard, custom colors available as an upgrade.

Whipple’s team is now the first to bring you the most powerful, 50-state legal, intercooled twin-screw SC system for your GM LT 6.6L direct injected engine (L8T) 2500/3500 Heavy Duty truck. Featuring the record breaking, race dominating Gen5 twin screw supercharger, 112mm front feed inlet, cast-aluminum intake manifold and complete intercooler system. What does all this mean? How about 700 ft-lb of neck whipping, tire shredding torque!

These systems include everything needed to install the supercharger, but you must unlock your PCM. We offer all options for the tuning of your computer, click the blue "Choose Product Options" button to select the PCM unlock option. The tune provided with the PCM unlock will work for stock or catback only applications, other modifications such as larger throttle bodies, headers, off-road midpipes, etc. will require custom dyno tuning done locally.
