I have a AEM fuel rail and a ssx fuel pressure regulator. I just installed a fuel pressure gauge and I was wondering if someone would know a good psi to put it at?

i want to make sure I understand brian.

You are saying dont hook up the vaccuum to the FPR??

That's correct, Do not hook up the vacuum.

The K-series ECU doesn't want to see fuel pressure that fluctuates with vacuum.

Yes

thanks for the info . I had it set at 58 psi. when you talk about the vacum line are you talking about the gold little prong that sticks out at the top where you adjust the pressure. Also what will cause my car to idle up and down when setting still

Air in the cooling system, or a vacuum leak, or a cable that too tight.

Mine has been running fine.

I will try it and see if any differences tomorrow.

Reset your ECU too just for kicks.
