Default Fuel Pressure

ok, so i put on my adjustable FPR today, and set my pressure at about 30psi vacuum off, and this seemed to make it run better than when it was set at about 40. My car smelled as if it was running way rich at 40psi, so I had to drop it.

What should my pressure be at for my mods??? I'm thinking it may be pretty lean now at WOT.

Iam pretty sure I run mine close to 40psi, and it runs great, you may want to check your o2 sensors if it seems its running rich, but then again, just check the plugs, and keep trying different pressures. Trial and error my friend.

I think I'm still running mine at 40 psi, even with the mods listed below, but I'd have to double check.
