Whats the stock fuel preasure regulator set for? Also, I picked up a adj regulator. What psi should I set it at?

i think stock is somewhere near 30psi with the vacuum disconnected.
not sure what you should set it at but a dyno with air/fuel monitering will get it perfect for you. or just play with it go for a drive and repeat until you feel it start to worsen

I got an air/fule gauge hooked up and now order a fuel preasure gauge. Just a lil one that goes on the fuel rail.

40 psi, vacuum off, about 32-34 vacuum attached.

Well the reason you would get an adjustable regulator is to ADJUST the fuel pressure like was said. Go out and tinker with it and see what kind of results you get.

I set the reg on 40psi! 45psi without!
