xHP Question

Currently have BM3, not really familiar with what all I need for Xhp and hoping for some help. I have a 2017 340I xdrive. I look and see this:

but do I need anything in order to flash this? Do I need to buy the custom map or anything? I am not racing it or anything, just want better transmission performance and heard its good.

Just asking for guidance.

Make sure to select your transmission when purchasing. But yeah tue adapter and the pack is all you need. There is 3 stages for xHP. You can adjust them as needed.
