Default Engine run-on

Howdy, I have a 2014, m7, z51, completely stock.
I’ve noticed that when I accelerate moderately or more, when I lift off the gas, it stays at that RPM for about a half second before it reduces.
I expect this is “normal” for stock but any other ideas on how to get it to reduce RPM immediately?
(Maybe it’s the stock tune)

Most modern engines are tuned to keep RPM up for a little while to prevent the formation of NOx.

That and the flywheel/clutch assembly in these weighs eleven billion pounds, which makes the transition from throttle to idle and revving from idle take forever....
