They actually have a compressor map comparison of the stock turbo to Garrett's setups (not sure how they got it or if they tested or what... but going by what everyone says, it seems to match up pretty well with what it should do.)
If that is correct... its definitely one awesome map for what I need.

But the lbs/min limits are the same as on holset's website.
None of the maps are showing what we really would like to see...the efficiency islands! Thats where holset, in my opinion, is superior to any other turbo. I believe their effeciency islands on the HX series are very wide! But theres no way to prove it without the proper map.
I would like to make a page with all the Holset maps floating around the web. You'd be surprised what I found.
