Default Fuel Pressure Question

How many pounds should I run my fuel pressure at on my 1994 JDM B16a DOHC VTEC Motor. It has Skunk 2 cam's, AEM cam gears, Fluidyne Radiator, full intake upgrade, full performance exhaust, AEM Adjustable FPR, Competition Fuel rail, Nology Plugs and a custom chipped ecu with VTEC Crossover set at 5400 and Rev Limit at 9000.
Thanks in advance

I would set it to the stock fuel pressure settings 38-40psi I believe and leave it till you can check it on a dyno. Chipped ecu's tend to run a little rich as it is so adding more fuel isn't going to help. You need to see what your air fuel ratio looks like before you make any adjustments over stock settings.

I had my chip set to stock fuel ignition tables before the vtec crossover, and aggressive ones after it. I used to run to rich before the crossover but now I think it's fine, I just want to make sure it has all the fuel it needs for after the crossover, soon I'll be changing the chip to slightly more aggressive fuel ignition tables before the crossover, stock sux. Anywayz, what would you reccomend then, still the same?

yes I would...always start out with the stock settings and then check the car out on a dyno to see how the air/fuel curve looks. That's the only real way to determine wen and how much the fuel settings should be changed for maximum power and reliability. If not you're just guessing and bad things can happen.
