When you want your Duramax to produce the "Max" possible power, you want the PPE Duramaximizer. Designed for racing engines equipped with PPEs Dual Fueler CP3 Pump Kit, the Duramaximizer provides up to an additional 100 hp and 180 ft. lbs. of torque by allowing for additional fuel pressure to be dialed into the fuel system beyond what is requested by the factory PCM. Providing a true "kick in the pants" feeling, it is activated only above the 70% throttle position that the driver determines. Setting the unit is easily done with just the turn of a knob, and tuning can be done on the fly. It even lowers the EGTs at the same time!
Allows maximum psi to be achieved from single or dual CP3 fuel
*Note: When ordering, please specify whether you have factory fog lights or a passenger air bag switch. This information is used to select the control knob location kit.
