Isspro EV2 Electronic Fuel Rail Pressure Gauge R42000-Style

Many fueling boxes raise the rail pressure for Duramax engines to increase horsepower, but can also cause damage to your expensive CP3 injection pump. On the other hand, larger injectors, and modified CP3's can also cause too little pressure to be built into the rail, causing damage again. Drive and race with confidence knowing that your fuel rail is not being starved or overfed with this fuel rail pressure gauge from ISSPRO.EV² electronic gauges also include an integral programmable warning light, which may be activated if you select the checkbox above to add the programmer tool. The programmer can also be used to adjust the backlighting curve to perfectly match the factory dash lights, and can also adjust the amount of signal filtering/smoothing that the software performs.
