That is interesting,
I did run the MC control pressure regulator (one with no vacuum lines going to
it) with the Ur-q fuel distributor (and lines and injectors).

It would go all the way to red at anything above 7psi (brand new O2 sensor).
Now with the MC fuel distributor lines and injectors (fine thread) all is well.

Under boost anything over 7psi the FV goes to above 60% and the gauge goes well
into green almost all the way to the limit.
I am running 13.4-14psi (depends on how cold it is outside) and it's nicely all
the way in the green (even if the full throttle switch is not engaged).

FYI I am not running any of the fuel evap. systems and crankcase vent is out to
the atmosphere.
