Well, I've gone through a number of posts here in this thread, but perhaps I missed some due to the total pages to flip through (currently 48). Out of curiosity, my2021 GT there are two separate tunes. A "US" specific tune, and what appears to be a rest of the world tune, of sorts. I've uploaded a screenshot. As I noticed earlier in the thread posts someone from Alabama loading up a non-US version map. Why would I want to, not want to load a country-specific map? In other words, is one map providing more power than the other? Cuz if so, I want that map!
