The ultimate engineering upgrade for 24-valve turbo-diesels, PowerPack marries Banks High-Ram air-inlet casting and the highest Big Hoss Diesel Tuner calibration to the Stinger system. With additional airflow and boost available to the intake valves through this final improvement, Banks calibrates the Big Hoss features to reshape air and fuel curves for maximum horsepower and torque - translating to top gains of +100 hp and +210 lb-ft torque - with 12% better mileage and prolonged engine life.
