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?.
