Comp Box - Edge Products

The true original in VP44 tuning performance.

The Edge Comp box is one of our longest standing product lines, with nearly 20 years on the market, and maximizes engine efficiency by monitoring the RPM, timing, turbo boost pressure, and fueling parameters of your 5.9L Cummins engine. The Comp module uses this information to determine and control both fueling and timing enhancements for the injection pump. Timing and fueling enhancements are controlled via CAN-BUS through the Data Link and by connecting directly into the Bosch fuel injection pump. The Edge Comp and Comp Hot are available for 1998.5-2002 24V Cummins and feature five power levels with power gains from 40-130 horsepower. Each of the levels has five independent adjustable sub-levels to control low boost fueling, providing a total of 25 levels of adjustability! The responsiveness settings enable you to dial-in the optimum balance between responsiveness and low boost smoke control no matter what additional power modifications have been made to the engine. The Comp module is fully adjustable on-the-fly and mounts inside the cab.
