BTW when I got the truck out of the shop in CA It threw 14 errors on the way home. With the help on this site and what was learned with carefully worded questions to Cummins support, I did the EGR tune up, replaced key sensors and went from 14 codes to 3 in my own driveway. Basically clean up of minion mistakes. The remainder issues are a ghost code most likely related to a electrical issue (code shouldnt apply to my ESN), an ongoing intermittent intake throttle actuator (original unit needs to be replaced as its noisy during zeroing and sometimes flutters) and the TSB calibration adjustment. Fuel milage is down, new sensors put in today, so will see. Also the last shop did an overhead adjustments and may have set wrong.
