Commonly known as a "cam plate", BD's Fuel Stop Plate controls the rack travel, which affects the amount of fuel the Bosch P7100 fuel pump delivers. Six different ramp designs enable power gains from 30 to 150 hp and 70 to 300 lb.-ft. of torque. A calibrated boost tube orifice is included to improve turbo performance. Strong knowledge of the Bosch P7100 pump is required for installation.
