Default fuel pressure/nitrous question

search isn't working :D

my setup:
96 civic EX
JDM B18C(1)
skunk 2 intake mani
intake
4-1 header
test pipe
2.25 exhaust
walbro 255lph fuel pump
b&m fuel pressure regulator and gauge
VAFC
ngk BKR7E's
NX single fogger (75 shot wet)

my question is...about where should my fuel pressure be right now? at idle before i put on the fpr, my fuel pressure was at like 52....is this high? right now i've got it set to be at 52 at idle and it's at 58-60 with the vaccum line off. i thought stock pressure was at like 55 at WOT....mine was almost there at idle...any suggestions? i want it to be safe on and off the bottle.

i'm going to be getting it dyno tuned in about a month when i get my itr cams and gears, but i want to be able to drive it happily until then...any help is much appreciated.
later

I think stock pressure on a B18C1 48-55psi. 60 psi should be fine. You can go to 62 psi with the vac line off to be on the safe side until you get it dyno tuned. Make sure to tune on a dyno with a wideband o2.

I'd upgrade to 2.5 inch exhaust piping.
