Well i got my truck back today -new EGR valve and Mass Air Flow sensor and they did the PCM\ECM updates per TSB 18-101-22. I tried a couple of time to get it to miss, so far so GOOD! I will say it seems to run better as well. I read thru the TSB and with the exception of no MIL Light - several of the things in that TSB fit my truck. It missed occasionally, the DEF use was up since the Y78 recall, i had codes fro cyc3, 6 & multiple missfires (NO MIL LIGHT), all addressed by this tsb flashing.
I have a trip with the camper next week, if it doesn't miss before then, and i make that short trip without a miss, i will be a HAPPY CAMPER!
