cpc stage 1 lost fuel pressure

just installed cpc stage 1 had adjusted fuel pressure to 38 in shop when I got ready to ride it would idle really high checked fuel pressure and all it would read is 12 how did I lose my fuel pressure

I'm thinking maybe its the fpr looks like there is a lot of fuel coming back into the tank though the return line

pull the reg apart, very easy to do btw, and clean the o ring, making sure the spring is seated well at the same time. Mine (my 11) was varying one day about a week after I got it & that was it, never happened again.
