    in case anyone cares, lol..swapped an acm and that did nothing. I have a good suspicion this is EGR related. lately my soot level will go to 100%, it will actually do a passive at this point, but never before 100%. It will drop the soot level down to about the 2nd "e" in Soot Level Gauge in about 80 miles. Then I get the check engine light with the SPN 2659 code telling me I have low EGR flow. I clear the code and do it all over again. I have replaced EVERYTHING on the EGR system except wiring and whatever is controlling it. EGR Valve,Cooler,update Venturi Pipe,EGR pressure sensor.

    The cooler is either plugged and needs to be cleaned possible the venturi ports might be blocked. even if its new doesn't mean #### anymore.

    I just took the tubes completely off going to the egr pressure sensor. again, the pressure sensor had water in it. cleaned out the tubes, and everywhere I could get to. There was soot, but that is to be expected. Is there any easy way to determine if egr cooler is clogged? I am at the point of either delete or going to chicago next month...

    Even if you get rid of everything there is no right way to do it by disabling egr there is a lot more bad than good out there so be very careful with who tunes your truck there is no proper way to tune a d13 no matter what anyone says all the good ones to my knowledge use egr valve and do not disable it. Take off the pipe going from cooler to Venturi and send me some pics let me what your cooler looks like inside. If you have bad injectors or a bad egr valve a delta p that is lying on the values you will plug up a new cooler in a matter of 2-4 weeks running like that. Just swapped one for a clean one today the truck just got 200k bought brand new already plugged up cooler u got my number let me know if I can be of any help.
