Ok, so i noticed my fuel pressure was going up each day off my b & m gauge. The set up is a jdm b16 brian crower stg 2 cams and vale train. Some aftermarket FPR and a AEM fuel rail, my fuel pressure is supposed to be at around 45 right? well its at 80 lol i havent been driving the car, i check the lines and they were fine and even put a stock regulator on it and the fuel pressure was about the same. Im stumped, could it be the fuel pump or something? HELP
