Engine miss or stumble at low rpms in the morning

[johnnyroastbeef]

mine is a 2019 2500 with the Cummins. this is my first cummins so maybe this is normal?
I usually notice a what feels like a miss, or stumble, when I first start the truck in the morning and i'm driving at low speeds, stop and go.
From a stop it feels almost like an old carbeurator that has a partially clogged jet, and you have to give it more gas until it clears up.
Maybe i'm not letting it warm up enough?
Let me know your thoughts.

MY 2020 is smooth as silk from the Get Go. Never once felt a miss or stumble in 16 months.

There is a tsb for a pcm flash to fix that issue have you had the dealer update it?

 

[johnnyroastbeef]

so it's been to the dealer several times and they did flash it a while back. Do you happen to know the TSB #?
I mentioned the issue to the dealer the last time i was in and they dismissed it and said it was normal.
but i did have to educate the service tech on what a TSB even was, so i have little faith in this dealership.
