Agreed, but I know my baselines today as I monitor 4 exhaust temperature sensors.

The one I watch closest is #1 in the downpipe.

I never turn the truck off until this under 400* F.

Side note; the next 2 sensors (#2and #3) get very hot during Regen., up to 1800*F.

I wonder if the MM3 can monitor exhaust temp sensor #1.
