SR Fuel Pressure setting???

Hey all ive been doing some research on this matter about what settings the fuel pressure should be at, I do understand with a stock sr20det its set at 3 bar(43.5psi) with the vacuum off on the stock regulator and ive also seen people talk about running it at 4 bar... anyways i would like to know what mine should be set, i have the nismo fpr, aftermarket fuel pump, and 810cc injectors, motor is built and will be getting a tune here soon, is this something i should let the tuner know so he could mess with it, but really i want to know as well lol. im shooting for just over 300whp and wanting it to run a tad bit rich to be on the safe side... im just wondering what is best, running it on 3bar, 4bar??? would like to hear what others are running with a similar setup:

Head:
BC 264 cams with stock cam gears
BC springs and retainers
stock valves
freddy intake mani
silk road exhaust mani

Block:
86.5mm Mahle pistons
eagle rods
acl race bearings
power enterprise pe1420 turbo
