BD Fuel Stop Plate When you're looking for the last word in fuel system upgrades, look no further than BD's Fuel Stop Plate (FSP). Designed with input from over 20 engineers, the FSP controls the rack travel which effects the fuel quantity the Bosch P7100 fuel pump delivers-the heart of 5.9 liter 12 Valve Dodge-Cummins engine performance. Six different ramp designs enable power gains from 30 to 150 hp and 70 to 300 lb.-ft. of torque, and a calibrated boost tube orifice improves turbo performance. Combine this upgrade with a High RPM Governor kit and a new Over Flow valve for good smooth power right through 3,000 or even 4,000 RPM For power levels above 250 hp, BD recommends a larger 14 cm turbine housing and a free-flowing exhaust system and Intake system (like BD's X-Hale and X Intake systems) to compensate for increased intake and exhaust flow.
