BBK Fuel Pressure Regulator

Hi guys,

Ive got a BBK fuel pressure regulator (BBK 1707) on my stang (mods below in sig)...

I need to get the fuel pressure down to 39psi without vaccume (which i believe is stock) so the custome tune i have here will work. I have an auto meter electronic fuel pressure guage that was reading 42 psi with vaccume and over 50psi with the vaccue off.

My problem is that i cant get the fuel pressure down below 45psi with the vaccume off. I dont know if the FPR is broke, iit appears to function fine at other pressures but its imperative that i get down to 39.

Has anyone ever had this problem before, does it sound like a common broken FPR... if it is ill get another. It says on the summit site that thi thing should drop as far as 35psi..

any help would be greatly appreciated..

thanks
