Carbureted Bypass Regulators / Blow Through Carb / Boost Reference

I have one of your Carbureted bypass regulators, advertised to adjust from 3-14 PSI.  I have a blow through carb and am setting the system up for boost reference with 7 PSI at idle and 20 PSI boost.  Pressure needs to hit 27 PSI with boost reference, will it work or stop at 14 PSI?

It will work perfectly, raising fuel pressure with boost up to 27 PSI if the pump can support it. The regulator itself has no limit for boost reference, but as pressure increases, pump flow decreases. When the pump can’t meet the engine’s fuel demand, pressure will flatten and eventually drop. This is a pump/flow issue, not a regulator problem.
