I don't think 16 is out of range.(?) If I'm off base then someone please speak up.
With the dieselgate tune my numbers where closer and balanced(?) My Kerma are spread now, much like yours, now with Kerma. Good, bad or indifferent??
My temp quickly hits 180 in all ambient temps. Its bugged me but doesn't really seem an issue. My MPG is right on the epa #s though.
Did you mention active regen time & frequency?
Not 100% sure what dur. KW is telling me but some knowledgeable guru input would be appreciated. It could help us all and specifically may shed light for op's diag.
