fuel pressure reg. mod?? does it work??
i heard from a guy last night that if u pull the vacuum hose from the manifold to the fpr that the fpr can take in more air and gain some power......is this true????

its sucking in more air to the vacuum, which therefore increases the fuel psi. its basically tricking the fpr that the car is WOT all the time since theres no restrictive pressure from the intake manifold, just constant air suction.
on my fuel psi guage it shows that it increase a few psi when i have the vacuum off, but dont be cheap just get an adjustable FPR when you have the mods that require it.
