App Description
The COMP box has dominated the 1998.5-2002 24V Cummins market for two decades and put Edge Products on the map in the early diesel performance era. With so many VP44 trucks still on the road, we’ve revamped our COMP to offer dominating performance gains with the industry’s latest technology.
Our all-new Bluetooth wireless switch offers on-the-fly adjustability giving complete control over the driving experience. The mobile App offers fine tuning adjustment for low boost fueling, fuel delivery based on Accelerator Pedal Position, and timing to dial in your power curve for aftermarket injectors and larger turbo combinations.
Breathing new life into your 5.9L Cummins, COMP offers gains from 40-150 HP, 150-380 TQ, even more RPM, and power available for heavily modified applications.
