The BM3 tune, currently, and the Transmission tune are two separate tunes. With BM3, you are tuning the engine. XHP only tunes the transmission.

I’ve heard that BM3 might eventually add a transmission tune capability to their tune in the future, but with BM3 they usually have a setting you can toggle to prevent any hiccups. Kind of like how they have options for burble settings.

As far as stage 2 goes, it would help if you are doing a lot of spirited driving. You will be able to take advantage of the extra torque the tune provides. It’s also helpful with changing your shift points as well.
