In up here in jackson MS
I can tell you, there is 1 thing I have seen work but....
It will NOT last long
Our GM had us washing a few of them out with magic bubbles shower scrub and a water hose.. (yes i know, some dumb s**t lol)
they lasted about 2 months at best before they cracked..
But maybe its an option to get you running for a bit until you can get a delete or replacement
But that much soot you def have a problem be it the egr system or overfueling
Make sure to check those egr pressure sensor ports
If you need a laptop your welcome to mine if you get up this way I have Insite if you can find a "good" file for your truck
