I was watching some data trying to find the cause of a miss my wife noticed the other day. The engine is an 06 that I got from my dad. It still has the floorit cp3 pump on it (don't know what %) stock injectors and stock tune. the only modifications are a colt cam, and a heater grid delete. I noticed that at idle desired pressure is 6600 and actual fuel pressure is in the 14-15000 psi range. Fca current is near the max and fca actual duty cycle is in the negative most of the time. Is this due to the modified cp3? it seems like the FCA can't get the fuel pressure down where it should be. Any advice would be greatly appreciated
