I assume the pump controller is running in fail safe and your pressure is just the tolerance of the in-tank regulator.

Fuel pump control ECU is bypassed per Kpower’s install, so I would assume voltage is maxed. It could change with rpms if voltage changes. I didn’t video the gauge while revving the engine. Or maybe the regulator changes based on demand by the ECU? I don’t know. Either way, I plan to add the fuel pressure sensor, so if the fuel pressure changes the ECU can compensate.
