Installed a Zex dry kit on a buddies 95 Gt. Everything is ran correctly and it is spraying at WOT but were not feeling the boost. We have the 100 shot jets in right now. The Zex box is supposed to raise the fuel pressure accordingly while spraying by having a vacume line running from the FPR to the box then from the box to the intake manifold vacume port that the FPR was hooked to. The max fuel pressure im getting at idle is 35 and it goes to 40psi max when we rev to redline. Any ideas? We have colder plugs gapped at .35 and a fuel pump booster installed.
