Some interesting data regarding pre/post EGR recal data for differences in EGR Duty Cycle and exhaust gas temps for my drive to work. There's a big difference in these characteristics. Not sure I like the extra EGR utilization to increase average DPF temps. Thought perhaps the recall added some post injection to increase DPF temps, but it appears it's just more EGR . . .
