fuel psi on a duramax LB7

the pressure will drop, 10psi at idle is fine, the injectors alone dont make a difference in the supply pressure to the cp3. the cp3 will flow what it can and even with stock injectors, the tuning you use will demand the cp3 to flow more/less, drawing more fuel to keep up with demands.
that being said having positive pressure is alot better then none. Mine has been as low as 4psi but i have under wot with a full tank, and i have seen it with no pressure due to the fuel sloshing around in a nearly empty tank
