id like to know more info on the egr tune up you speak about?

If your not doing EGR tune-up work, its like trying to use a buckjet to get the water oput of the bottom of your sinking boat... all while the drain plug is letting all the water in to begin with.

I.E.> Fix the source of the problem (EGR tune-up work)..and not just simply the aftermath of it (the now clogged up emissions cans).

I know on our 6.7s if you change a few parameters in the ECM for after treatment the issue cut in half.

Not sure what your implying... are you getting the 6.7's de-mandated?.. are they being made more lenient with aft. systems still in place, still can regen, etc. thru a few custom setting changes ?. ? .. or something else?.

No these are not de-mandated. Completely stock what happens when you enable the temp stabilization parameter in the ECM it allows the DPF system to regen at a much lower speed versus your typical 45mph. It locks the DPF in a “keep warm” cycle (best way to describe it) till soot burn out is complete. So basically if you drop below 5mph it will kick the regen out and if you run a delivery truck or school school bus that does a lot of starting and stopping you can set your regen speed to 1mph and as long as the wheels are rolling you will continue to regen
