A few of us have the GTB2056VK, not heard of any 2260s though. There are a few 2260s in BEW cars running around here.
For a daily driver I am glad I went with the 2056. It is a little laggy compared to stock but not too bad. I'd say it is actually less laggy than OE turbo with a worn VNT. I question the wisdom of going as big as a 2260 in a PD, the head is prone to cracking around valve seats and injector bores as it is.
