Base fuel pressure with 2g FWD eclipse with 1g engine

[alqatan]

Actually I have 660 cc injector+walbro fuel pump 255 high pressure my base fuel pressure is 44 psi, is this normal?

Should I go lower because I've heared with 1g engine I should be 38 psi or 36 psi, but with 2g engine I should be 44 or 43, I've heared with walbro fuel pump the fuel pressure will rise like 6 psi more than stock does this mean my fuel pressure turned down to 38 psi because of my 1g engine and because of my walbro pump it went back to 44 psi.

Actually I have fp3065 turbo kit and running high boost, is it possible to decrease the fuel pressure to 38 psi or lower than that so I don't lean it out alot at high rpms and the timing will be fool

What fuel pressure I should be in with 1g engine on 2g 1997 eclipse and what is the lowest level I could decrease with 720 cc injectors?

Thanks

I don't know if this will help you or not but I got it from VFAQ-

" the 1G Turbo FPRs are rated at 36.3psi at zero psi, the 2G Turbo FPRs are rated at 43.6psi at zero psi. What this means is that at idle (assuming a healthy engine with stock cams, which should have roughly 18-20" of vacuum), 1G/2G NT fuel pressure should be around 39psi, the 1G turbos should be around 27psi, and 2G turbos should be around 35pi (because 2" vacuum equals roughly 1psi). On a 1G turbo, you should have roughly 41psi at 5psi boost, and 51psi at 15psi boost "

Go with 43 psi. I am running 660's and walbro 255. I have no problem with tuning. I'm tuned for 20 psi PUMP 91 Crap Gas.

Thanks guys I didn't check my fuel pressure with no vacum, mean I didn't remove the hose connected to it, when I removed that it was like 51 psi, I guess my stock fuel pressure regualtor had a problem now I removed my stock one and put back my fuel pressure to 43 psi, the low throttel feel much better and easy to tune

Thanks for your help.
