Hi guys so I just joined this site. My issue is the code listed in my title 2DED- closed circuit. When this code displays my HPFP drops pressure. I have seen my trims go higher than 30 on the jb4 log. I have a LPFP stock with a second pump connect to the battery. It is then relayed to the JB4 controller which is also my PI controller with two wires. Can this cause the issue? Maybe installing a hobbs switch can fix the issue? The car AFRs start running very lean when cruising as well and bog.

I have the same issue, but no PI. Did you find the problem?
