Fuel Pressure Gauge Question

Fuel Pressure Gauge Question
I FINALLY installed an Isspro EV mechanical fuel pressure gauge and Big Line Kit. I got all of the air out of the isolator to gauge line. With only two years time on my Raptor lift pump, I show to only have 11psi at idle. WOT pressure drops to 8. Question is, do I have an incorrect reading at the gauge, or do I turn the pump pressure up? Any suggestions will be appreciated.
