You won't get the latest but there have been at least two PCM firmware updates for MY2020 that will help shifting some. Unfortunately, you need to still be under warranty and even then it is up to the discretion of your dealer whether they want to flash the latest. Since early 2020 builds have over a dozen modules with new updates, a few of us have bought the interface and leased FDRS software to flash the module updates at home. Not cheap but certainly an option, especially if you are out of warranty and are keeping the vehicle a while more.
Also, a lot of the tunes make full throttle shifting quicker, stronger, smoother than stock but may not address the ungainly day-to-day, partial throttle shifting that can occur with the stock calibration.

I just imagine if I asked the service writer about any of this they’d look at me like I was speaking Greek and out of my mind. It’d probably be easier just to get the FP tune, though I’d have to figure out an ASE mechanic that would install it for me.
I’m just spinning my wheels. Would the tune basically give me all the shifting improvements and basic throttle improvements that the new firmware might give?
