X-Power Plus module for the 2003-2004 Dodge-Cummins offers what no other electronic performance product can: State-of-the-art technology, serious power and ultimate control—all without compromise! Unlike other products that raise fuel pressure to increase fuel delivery (which can cause leaks and damage to fuel system components), the X-Power Plus achieves performance gains by altering injector pulse duration and timing. A stronger, longer combustion event means more boost and more power—up to 180 HP at the rear wheels! A cab-mounted, color-coded Power Dial allows progressive control in any one of three power levels. Comes complete with BD's Boost and Pyro X-Monitor digital gauge pack.
