My truck is throwing the p0193 code which is rail pressure sensor high . My quadzilla gauge says at idle 5500 and with cruise set at 65 it's reading 13500 also hooked it up to a snap on scanner and it reads the same . What could cause this I don't think that the pressure is high . Truck runs fine I noticed yesterday and this morning the first start is rough and this morning it actually died after it started. Truck has 235k diablo predator on 90hp tune cai blade runner intake an 50hp injectors the quadzilla is just hooked up for rail pressure gauge
