Tuning has always been the obstacle with supercharging the latest GM cars and trucks. From 2019, the light-duty Chevrolet Silverado and GMC Sierra switched to a new, tough-to-hack electrical architecture that made recalibrating the Powertrain Control Module (PCM) seem all but impossible.
Whipple has gotten around that, it seems, by partnering with HPTuners for the PCM tuning, leaving the company to focus wholly on developing the blower.
Whipple’s new 3.0L unit is based on its latest fifth-generation twin-screw supercharger technology, capable of reaching over 100% volumetric efficiency. It has a big dual-pass heat exchanger for cooling the intake charge, and included with the kit are a high-flow aluminum intake manifold, an adjustable idler system with a billet idler plate, and an upgraded spring-loaded tensioner.
