Lag

2020 3500 HO aisin here. Theres a lag between 2nd and 3rd during mild acceleration and I'm assuming its torque management. Anyway to get rid of it or just live with it?

Lag or shift flare? Either way, leave it be, IMHO.

On mine there is a sort of "double tap" hesitation that seems to be the converter locking. Feels like it begins to lock, unlocks, then locks up. That 2-3 shift is where I was getting some serious shudder when pulling the toy hauler. The last reflash tidied up some of the empty behavior. If yours is a '20 I assume you have the latest software.

No way to get rid of it and still maintain your warranty.
Best to just get used to it.

I bought a Pedal Commander a while back. It is listed as adjusting your throttle response, however I believe it affects the torque management in some way. I cant prove it and its just "my feeling" but it has a seat of the pants feel of more than just adding in more throttle with less press of the pedal. It is smooth, yet very responsive. The transmission learns so I actually ended up turning mine down after a week or two, now it is perfect and far from its highest setting.

I did not want a race car, I just wanted it to go when I wanted it to. My truck is a pleasure to drive now. It is not just "peppier" but the shifts throughout the range are better also. Thats the main reason I believe it effects torque management in some way, whether intended or not. There are a few different brands out there, the Pedal Commander is the only one I tried. It may or may not be the solution for you, but there are options.
