The Comp Box has dominated the 1998.5-2002 24V market for two decades and is what put Edge Products on the map in the early diesel performance era. With so many VP44 trucks still on the road, we've completely revamped our Comp to offer those same dominating power and torque gains with the industry's latest technology. The new Bluetooth wireless switch offers adjustability on-the-fly while the available smartphone app offers fine tuning control over fueling and timing settings. Dial in power curves for aftermarket injectors and larger turbo combinations with better control over smoke output. Comp offers power gains from 40-180hp over stock with factory fueling, with even more RPM and power available for heavily modified applications. Whether you're on the street or the track, if you want to feel the real adrenaline rush from your VP44 truck, the all-new Comp out fuel's the competition.
