Installed a aftermarket FPR, does anyone know what the stock fuel pressure is?

thanks!

 

38-46 PSI with the manifold vacuum line disconnected.

 

At some point around the time OBII came along most makes standardized pressure at 43.5 psi too. Its hard to go wrong with that as a base pressure.

 

Thanks ya'll. Took the beast out for a run with just a base map and a few lbs of boost. Holy **** this thing is fast. I can definitely tell the difference between the old shitty 94 head the the ported +1 valved FM MSM head. Can't wait to tune this bugger.
