I see the new vehicle list states...

2020 Dodge Durango 3.6, 5.7, and 6.4L

I must assume that includes my 2020 Dodge Durango R/T 5.7 although that trim is not specifically called out.

1. So I would first need an MPVI2 and a bypass cable to read my stock system and upload that when when its time to order an unlocked PCM?

2. I think I saw that they have a package that includes a new unlocked pcm, a bypass cable and the MPVI2 but can't seem to find the link.

3. When returning to the dealer for warranty service, is it best to leave the unlocked PCM in place, return to stock tune, and uncheck the P1400 code.

4. If the dealer has an update flash would the unlocked PCM be able to accept it, and then I would read the new patch as my baseline for tuning forwards.

I am just trying to get my arms around a strategy that gives me some tuning capability while striving for the best possible outcome at my dealership.

Many thanks to anyone who can help me with these questions, as it will surely help me to muster the confidence I need the to take the plunge!
