Re: 85 lwb turbo 5.3 build

Your fuel pressure should rise at a 1:1 ratio with boost.

Example: If your base fuel pressure is 58 psi, at 1 psi of boost, it should be 59 psi and at 10 psi boost, it should be 68 psi.

Doing it this way makes it easier to tune, since your injector flow should remain constant.
