Low Fuel Pressure Target At idle

Hello everyone, with the addition of a low fuel pressure sensor via the Reflex, I've been observing oscillations at idle along with the occasional low fuel pressure code, however above idle it ranges between 100 to 110 psi. I assumed the swings in pressure were due to the DME making adjustments to the pair of 450's through the BPM4, does anyone know exactly what pressure number (psi) I should be looking for?

For anyone who may have similar issues and or questions, I was having issues with my wiring from the BPM4 harness to the pumps which was causing some shorting/feedback, ensure that the wire you use in the fuel tank is fuel resistant! after fixing the issue the average (lowest) pressure I observed at idle was around 86 psi.
