CM871 Slow Climbing Regen Temps

[Taco05]

Last few days regens were all between 3-4.5 inHg and they were all about an hour apart.
these are the numbers when I did a forced regen yesterday.

EGR Diff pressure .0 inHg
EGR Valve position 0%
Exhaust gas pressure 146 inHg
Intake manifold pressure 13.2 inHg
Percent load 0%
Turbo position 88%
Turbo Speed 45325

Aftertreatment Differential pressure was at 2.3 during regen and after 5 min I was only at about 650F for both rear temp. Regen lasted about 40 min and peak temp were both over 1000F.

Calibration has been performed last night by cummins and they also did a snap test which they stated the truck has passed. Truck is doing a short run and should be back tomorrow I will forced it again and compare numbers.

Guys thank you very much for your time and knowledge it is very much appreciated !
