It allows a 25psi idle fuel pressure with a Walbro GSS-342 fuel pump!

The stock FPR would keep minimum FP in the 50's.

Greg, if you don't mind me asking, what's the benefit of lowering the fuel pressure? Is idling at 50psi just wasting gas or what lse?

[Holden]

"Is idling at 50psi just wasting gas or what else?"

Not only will it waste gas, but you'd also have the following effects:

1) Throw codes for being too rich
2) Foul spark plugs
3) Blacken your rear bumper
4) Driving under 6psi boost (which is where MY fuel requirements reach 50psi) will be too rich and rob power.

The problem (I think) is that the ECU can't reduce the injector duty cycle enough to compensate for 50psi on 320cc injectors when running w/o boost.
