Product details
This isnt just another plug in chip that floods your engine with raw diesel and covers the car behind you in black smoke. These systems are engineered to be the safest way to boost horsepower on any diesel engine. NXd systems actually cool the exhaust temperatures while boosting horsepower and torque! The Maximizer nitrous controller allows you to apply nitrous flow according to boost levels, RPM based delivery, Time based, MPH (Miles Per Hour), and Throttle percentage progression. Infinitely adjustable power levels make the NXd system the most advanced, safest diesel power booster on the planet. The NXD4000 works on all Turbo diesel applications. The NXD4000 nitrous system includes two Pro Power Lightning solenoids (.120 orifice), 2 dry nozzles, -6 feed line, 15 lb. bottle, and a boost reference progressive controller.
