cant get more than 60psi under WOT with dual walbros. So I'm having problems with my twin 340s intank walbros.
I can't get any more than 60psi of fuel pressure under WOT.
I have -6 feed and -6 return .
1:1 boost referenced regulator.
Base pressure set high doesn't help either. It will always drop back to 60psi.
I had one fuel pump fail on me and was only getting 30psi of fuel pressure (thank god for e85).
Came to the conclusion that it seems like i won't be seeing more than 60psi with both of the walbros.
My 80lb injectors are at 90% IDC on e85 currently. I need a little bit more of fuel pressure to give them some room
Any thoughts?

As I said in your last thread. Draw a schematic of exactly how your system is put together, including all junctions, wiring etc etc.
It will be the easiest way to try and remotely diagnose.
Pressure dropping back could be a lack of flow, but lack of flow can be caused by many things.
