Default b18c5 fuel pressure

Does anybody know what the ideal fuel pressure is to run on a b18c5, with a msd ignition and full exhaust and a 255 fuel pump. I dont want to starve the motor but i dont want to load it up either. My air fuel ratio guage jumps into lean everytime i put it into vtec.

MSD igntion = waste of money

I'd set the fuel pressure where ever it makes the most power on a dyno.

Oh and that a/f guage is nothing to base your concerns on, because they are usually wrong anyways.
