[F-450 Man]

Hello everyone, I was curious if anyone has any knowledge about doing a DPF delete while keeping all the other emissions stuff on the truck? From looking at the DPF I don’t see why you couldn’t just remove it and leave everything else stock without a tune. If the truck doesn’t sense increased back pressure because the DPF is gone then it theoretically should never do a regeneration. I have a banks tuner and don’t want to deal with stacking it with another tune to delete the EGR and DPF codes. I want to leave the EGR system as is.

Deletes are hard to come by these days. No matter what you do to this truck It needs a tune. Remove the EGR and it needs a tune. There is no reason to spend money on something that isn't broken.

Lol you likely wouldn't make it one mile before the truck realized the dpf was gone. Ever heard of a NOX sensor?

Unfortunately the monitoring is not that simple, take a look at the section on Catalyst & After treatment monitors in the attached article for some insight into how the programming functions.
