BD’s X-Power Plus module for the 2003-2005 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
