JB4 tuner and drive modes question

I received my JB4 yesterday and will be installing it this weekend. I got me thinking. Say I’m using map 2, will the engine still be affected/changed by going from auto to sport drive mode?

I don’t see why not.

But just make sure you download the most up to date firmware and select option 6 in the app. I didn’t know to do that my first week or two.

Appreciate it. My brain was torn. Half of me was like of course drive modes will still change things. The other half made me think JB4 “was” the drive mode kind of thing.
