My old '03 PS did the same thing. Went to normal idle after awhile of running or by stepping on brake pedal to move from park. However, on my '15 PS, it too goes to high idle (both after being plugged in), BUT it will not go to normal idle after stepping on park to move from park. Tho I have the PS and you have a Cummins, I'd say it's normal.
Just wish I could figure out how to raise idle when stopped for a lengthy time. Semis use the cruise to do it.
On my 06 PS I used one of the accessory switches for the high idle. Under the driver's side dash to the left of the steering wheel there was a wiring harness. One of the wires was for high idle. Wired that to the first accessory switch and I was able to high idle my truck. Check the internet I'm sure there's a link on how to do it.
