Error codes/ FICM?

Totally fine. It's when voltage starts slipping lower like 45V or even lower that will toast your injectors.

Thanks everyone. It was indeed the FCIM. Voltage was at about 29v. Check wires, harnesses, battery connections, fuses etc while we were in there. I shopped it pretty hard but eventually talked with enough people that I felt comfortable taking it to EIS Diesel in PDX. Felt very good about my experience. Guatemala here I come!

Whoa. 29V is very low. I would be surprised if that didn't damage the injectors. I'd recommend monitoring injector duty cycle under high load, and also cylinder contribution (aka cylinder balance).
