Yeah Ive got the base fuel pressure set right. At idle its about 52 psi. I set htis while my fuel pressure guage from hahn was working and i haven't changed it. Last night I turned the brass nob out to 1 and 1/4 turns and now it seems to work fine. My a/f reads lean under boost but the cars drives well with this setting, but you said this happens to you also. As for the auto meter fuel pressure guage I have no idea why it would not work, its simple to install. Thats what im going to do today, maybe ill just get a different guage and see if that one works.
