Re: Can i turn up my fuel pump?

it will give you a tad more power. if you put in a shim it's opening up the regulator more and allowing a little more fuel. that's the point of the shim. stock fuel pressure is somewhere between 55-58psi. with the bigger shim it will get it up to 65-70psi. your truck will idle a little smoother and deliver a little more fuel constantly. as for the smoke you're gonna have to drop some $$$$.

that is incorrect. the pressure regulator is a bleed device that keeps pressure in the filter housing and injector supply lines. the shim increases the preload on the spring to keep the plug seated on the valve seat when the fuel pressure is applied to it. that valve bleeds back to the tank.
