Message A little confused on the middle two below (completely different maps). If the GT2560R is the turbo previously known as "GT28R", then what is the GT2860R?

GT2554R <-- 530BB
GT2560R
GT2860R
GT2860RS <-- 700BB (disco potato)

On paper the GT2860R has a larger trim (62mm vs. 60mm), but according to the map it looks like it will flow more and spin faster, with max PR exceeding 3.

GT2860R:
