Fuel Pressure Regulator. Says 46 PSI to 52PSI with vacuum disconnected.

I know it should be around 39PSI.

I got the new BBK Fuel pressure regulator that claims 35psi to 70psi

i also installed the BBK Liquid-Filled Fuel Pressure Gauge AFTER I installed the new Fuel pressure regulator..... SO I DON'T know what it was before I did this

If i loosen the regulator till the top is off the lowest it will say on the gauge is 46psi.

What could be wrong?

I have 24lb fuel injectors. No matter the PSI wont the injectors limit what goes through?

I still want to fix this but just wondering.
