Cm2350 high commanded vgt

[Carhauler]

Ok, so I have logged the vgt and egr and various other parameters while driving, seems driving is fairly normal. Only idle is where is commands 80-90%. When egr starts to open it commands the highest and you can here the turbo whistle less from the drop in exhaust pressure.
There are no leaks in the egr system and the sensors and valve appear ok.

Did a regen last night. Dpf differential pressure ended up at .03 at idle. Didn’t take long either.

It has been pretty cold. 20-30 at night and 30-40 during the day.
When the Scr stays warm it seems to back off the vgt. Then it cools down and the cycle starts over.
Any ideas?
