I was wondering what kind of fuel pressure i should be running with my set up
Greddy turbo 8psi, rc 310cc injectors and walbro 255lph fuel pump, i have a y7 bottom stock and y8 head crower stage 1 cam and stock valve train. I installed the fuel pump and my pressure is 43/44psi i have a b+m adj fuel pressure reg and gauge i can turn up the pressure to 60psi max with the reg. but the lowest i can get it is 43/44psi.Any suggestions.

the 255 fuel pump brings your pressure to 43-44....cant go lower just higher with the regulator
but not to worry 43-44 is normal for a 255 fp

well the ? I think would be when you start to get on it and up inthe RPM's and close to WOT does it lean out at all on you? If you watch your B&M Guage when you rev it goes from 43/44 up to what??? This info might help as to what PSI the pressure goes to when getting on it.
Hope this may help out to get more info and god luck..

It jumps up like 5psi when i rev it. At WOT its at 48psi. The car feels better now at 6-8psi of boost it seemed to drag a bit before and not pull as much at higher boost.I just trying to find a good starting point but without a dyno in my driveway i can only go by feel and having to open it up a little on public roads isnt too easy.But thanks for the help guys.
