They didn't look to bad after I took them out the the cleaning test said they needed to be cleaned. Reassembled everything and did another parked regen. DPF outlet temp stayed about 50F above inlet temp during the entire regen.

The DPF thermal regeneration began at the experimental time of about 30 s, from which the target regeneration temperature and the DPF-inlet temperature started to increase gradually. As soon as the DPF-inlet temperature reached the target temperature of 575 °C, the throttle position was quickly reset and the engine dropped to idle.Jan 18, 2020 · Mack MP8 regen issues. 2012 CXU613 with 2012 fault codes so it's not a 2013.

Maybe 50 to 100 deg. F at best. The high temps are in the exhaust NOX/DPF filter. Everything upstream of that is pretty much normal from my observations. See this video on an entire active regeneration.
