Is the file stock to the truck? Was the DPF differential pressure sensor swapped out and tubes cleaned?? Can't imagine you running too far seeing 7 inhg... On a normal system you never want to see more then 3inhg..

Dad took the cooler off while i was driving the other truck, I'll ask him. But he was specifically looking for soot accumulation and blockages while installing the new EGR deltaP sensor and inspecting the cooler.

DPF deltaP...I haven't touched it yet or looked at its tubes. The deltaP values looked a lot better after the diesel shop baked the filter, so no, I haven't barked up that tree yet. Before the DPF bake, the truck was running fine. I took it to the diesel shop because of the derate imminent warning combined with the scary plugged DPF code.

I don't understand your question about a file being stock to the truck?

Thanks, marek!
