Fuel Pressure?
With stock Walbro pump, you'll see your pressure drop slightly. Ideal press is about 58/60. Adding a return line and regulator at the rails will allow this pump to maintain pressure and flow under heavy demand. Some using Racetronics pump and hot wire kit report a maintain 60 psi and no drop. Our stock pumps can support 550rwhp easily, but with a little fluctation because of return at tank.

I think my fuel filter may be restricted. My pressure at idle is down to around 52 as the rpm goes up, it gets to about 54-5, but it seems like it has dropped. I haven't done any WOT nitrous runs to see if it's dropping... Guess I should just change it out to be safe.
