I finally started driving my car alittle more. So I installed a new fuel pressure gauge. I set static pressure around 25 on 40# injectors but as soon as I hook up vaccum source fuel pressure Drops to 6#. Remove vaccum line and right back where it was set. If I try to adjust static screw while vaccume is connected it will not raise. It does raise fine under boost. Could this be from not having a vaccum restrictor. or does any one have any ideas? I dont remember what it did before. I stepped on the restrictor and broke it.

Almost forgot STFT and LTFT both look good STFT is +/- 6 and LTFT is -12. Im trying to get idle pressure set for 10-14 psi.

Adjust the fuel pressure with the static screw with the vac line connected. My sure you boost and vac screws and turned in and you have the sfmu put together correct.
