This upgrade adds the key airflow, fueling, boost, and calibration changes that separate Stage 2 from the standard Stage 1 setup. With 93 octane or higher, this upgrade is capable of adding up to an additional 50 horsepower and 20 lb-ft of torque under optimal conditions. The package includes a billet Whipple supercharger pulley for a 1 psi boost increase, a billet 132mm Whipple Roval throttle body, 132mm inlet air tube, Bosch 55 lb high-flow fuel injector set, and the updated Stage 2 calibration needed to support the increased airflow and output. This is a parts-and-calibration upgrade intended for existing Whipple Stage 1 customers who want the strongest airflow and fueling package available in the Stage 2 configuration. It provides a direct bolt-on path from Stage 1 to the highest-output setup in the Whipple F-150 lineup. The included calibration is supplied for reuse with the existing Tomahawk flash tool, provided the tool remains on the same VIN. That helps make this a cleaner upgrade path for current Whipple owners already running a compatible Stage 1 system.
