5 to 7 PSI at wot is fine. Should have 14-15 at idle. If your max egt is 650 then I'm guessing your probe isn't in the exaust manifold. Watch out, that is a false reading. You should add about 350 for pre turbo readings. I suggest you drill and tap your manifold and put your sensor there. Buy a fuel pressure gauge and check it every oil change or put one in the cab. Lift pumps are $160 from Cummins and can be changed in about 20 min with a little practice. I always carry a spare.

i have pyro, boost, and fuel pressure guages in the cab. cold air intake and a 4 inch exhaust from the turbo back...max boost at wot is 28, the hottest it gets is 650, and at wot fuel psi drops to 5-6...at idle its about 12-13..i'll have to look and see where they installed the probe

How much did your performance change Bern when you changed out the exhaust to the 4"?

My pyro runs about 530- 640 under normal running when I turn the fuel up to 63% over stock if will reach 1150+ for a second then the box defuels till it's under 1100.
