How smooth is smooth the warmed up idle on 2018+ trucks?

[smokey_mountain]

Some of you may know me already I am still riding the 2018 Yukon with rough idle. I need a good truck that has 3 rows and can pull a decent size camper and get off the pavement. The good tug is hard to get these days. 2020 Tahoes are sold for very good price now since everyone wants T1s.

With that those owners with 2019-2020 Tahoes do you feel your idle is completely buttery smooth or do you feel light "skips", flutter when in D and fully warmed after driving for for 20+ minutes?

No problem with my 19 denali

Denali is 6.2L though? Correct?

I have a 2019 callaway Tahoe, other than the callaway exhaust rumble, the engine is smooth as can be, runs great after 20 minutes, or the 343 mile trip each way I make each week to my other home, 20 minutes or 6 hours, still smooth

2019 Yukon Denali - Callaway: Same, buttery smooth idle. I think it's the 5.3 owners that complain about the rough idle though...

Thank you, very interesting to sample. BlackBear guys told me that 5.3 are so smooth these days, one should look at the tach to see if it is running, that was BlackBear's take on smooth. Justin has taken a look at the logs of my truck and plotted them. He registers issues on the plots but unsure what is causing it. Power of the crowd is always there, so I am asking for advice from experts here:
