The Comp Box has dominated the VP44 24V Cummins 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. Edge is committed to offering the best VP44 tuning available on the market today and the all-new Comp offers more fueling, more power, and more RPM than ever before! The new Bluetooth wireless switch offers adjustability on-the-fly while the available smartphone app offers fine tuning control over low boost fueling and timing settings. Comp allows users to dial in their power curve for aftermarket injectors and larger turbo combinations with smooth power curves and control over smoke output. Breathing new life into an old 5.9L Cummins, the Comp Box offers max power gains of up to +180hp/400ft-lbs with stock fueling with even more RPM and power available for heavily modified applications. Outfuel, out power and out RPM the competition with the all-new Comp Box!
