These new X-Power Ram modules from BD Diesel offer new performance technology for the common rail fuel system. The X-Power modules achieve performance gains by altering the duration timing of the injection pulse, and not by increasing the rail pressure, which has been known to cause fuel leakage and damage. The X-Power Ram modules also install easily by connecting to the factory injector plugs and MAP sensor. They have four adjustable preset power levels that produce increases of up to 130 hp and 240 ft.-lbs. of torque! They include the Power Dial, which gives progressive performance control, and come with a color-coded decal.
