Still holding up. But a few days ago it started saying my DPF was 80%, 90% full and then said full, power reduced, see dealer. I cleared all the codes and then put my Smarty back on. DPF still "full". Started driving around and it supposedly went into Regen and power was back. Got home and cleared the codes again. So we will see if it stays all good now my Smarty is back on.

That's strange. Was your DPF on?
Sometimes I'll get a message that says Exhaust Service Required, See Dealer Now. On my was to Texas a while back I think I got that message 3 times. I got that message again a couple weeks ago, but went away after the truck was shut off and restarted.
I have never got the X% full messages though.

Yep. The funny part about it, I updated the tuner to .26 then .27 that said that message was fixed. I returned to stock, reloaded, message went away, then came back. I updated about every other update, then updated to .36 while I was in TX. Didn't get the message again until I was headed home to NV. I am now on .38 and gave up on it actually being fixed. Hadn't felt the need to update since then since I haven't noticed an actual problem because of it.
