Well here is how it went down. Right after posting, I went back with ids and selected module programming. I verified the vin, and it instructed me to install a new module. What?? So I selected ok, and it programmed my ecm. Now my maf is correct at about 30 g/s at idle,
and up to 300 ish under load, depending on egr and load. DPF showed clean and I drove 12 miles to my turnaround and ran full load up a hill to 75 and dpf hit 4.8 psi max, great. the dpf pid showed part loaded for about .5 miles and then went back to clean and remained clean on my 25 mile drive and under full load was just under 5 psi. It appears everything is ok. For some reason the ecm MAF calculation was waaaay off and I believe injector timing, dpf calculations and egr operation were way off as well. I'm gonna ship it and keep my fingers crossed. By the way, it is a halliburton truck and has never had any power up software, although they run a connector to the dlc to monitor speed and acceleration for their black box.
