First thing you want to do is run it long enough that the battery is "up" and stable, and you want to be sure the VR and engine bay is up to normal temp. Many VR's are temperature sensitive. That is a tiny bit high, not sure I would worry
I've written tons of posts about voltage drop problems in the harness and ground circuit. That would be the next thing.
Mopar, so far as I know was the ONLY manufacturer who combined the field / VR power circuit with the SENSING circuit, which in part, is the root of the entire problem.
