What makes you think you are running too lean?
When performing the static test, the engine wants to eagerly rev past the redline.
Here's my conundrum:
My stock fuel pressure regulator is integrated in the fuel filter near the rear of the car, so the fuel pressure is regulated
before it hits the fuel rail (which is generally different from the norm). Now my WON system fuel source is tapped in the fuel rail, so in my case the WON fuel solenoid may see a lower fuel pressure at 2000 RPM = static test rpm; than during WOT.
This may be the reason why the static test appears to show a lean condition, which
may be totally safe at WOT.
I'm interested in what you guys think.
Regardless of WHERE the fuel pressure regulator is located, the fuel pressure will be the same at the injector. Most cars these days have this style of pressure regulation including my car. Your car may be modulating the amount of power at the pump in order to regulate pressure further for more precise fuel trimming.
What is the max rpm of your engine and what max rpm is it reaching during the test?
Also what jetting are you using again, 50bhp? The more jetting you use, the faster the engine will rev up.
I'm sure we can sort this out; your car may just not respond to the static test well and you may need to go to the road test to verify your jetting.
