Plenty of people using this turbo now. Garrett now calls it the GT2560R if I am not mistaken. It is also known as the JWT sport 700 aka disco potato. There are a few members of the 600HP club on z32power.com that are using these with very nice results
As far as going to the dyno be sure you go over the 6p's first 6p's
