[QUOTE="Blown38, post: 12937620, member: 88849"] You need to have the pressure raised when boost is in the manifold or your injectors will act as smaller injectors as the fuel pressure will be the same but you now have 18 psi working against the tip of the injector. You want to keep the delta pressure at the 39.15 psi. Which is the pressure in the manifold and the pressure in the rail working against each other to where the the fuel pressure at the injector tip is always 39.15 psi. I'm not very good at explaining things so if you don't understand what I am saying hopefully someone better will chime in. [/QUOTE]
