The behavior though from the logs looks pretty identical to mine if I was to disable my aux pump. I’m Having him try a few pulls in a higher gear, monitor the voltage from the JMS and see how the pressure is on 93 with the JMS disconnected.

Should be able to tell if it’s the JMS or the pump itself. If he had an aux, I would also Suspect a restriction in the filter from Drilling the tank. (Not the case here)
