Overview
The Whipple W140AX 2.3L Supercharger No Flash Tool Kit for 2004–2006 GM trucks and SUVs equipped with the 4.8L engine delivers instant, torque-rich power with proven Whipple twin-screw efficiency. This No Flash Tool (NFT) configuration does not include calibration, tuning credits, or a flash tool, making it ideal for customers who already have a custom tuning solution in place.
Built around Whipple’s W140AX 2.3L twin-screw supercharger, this complete intercooled system is capable of producing a 160+ horsepower increase on 91-octane fuel with approximately 7–8 psi of boost. The result is strong low-end torque, immediate throttle response, and consistent power delivery that dramatically improves towing, street driving, and overall drivability.
