They aren't secretive, just didn't want to put on the internet all day long. Its there, its a matter of finding a good part of the Cummins Turbo Technologies.
This is reagrding the Holset HX55 B98 series turbo
No. not even close. These are about 72lbs/min at 2.9PR at maximum speed 110,000rpms at about 68% efficiency
2.5PR = 38lbs/min at about 80,000rpms -- This is the sweet spot at 78% efficiency
2.8PR = 58lbs/min at about 90,000rpms -- Another good sweet spot at about 76% efficiency
I have access to some of the Cummins Turbo database as a consultant. They will not allow us to copy a PDF of sectioned maps. Actually, its very confusing going through even the site.

I'll be right at 2.5, thank you. I needed to confirm my pr was good. As to what I said earlier I think you misunderstood. I said .46kgs is ~60 lb/min. I.e. a reference of kgs vs. lb/min. But thank you for the very useful info. I'll be at 2.5 pr from ~5700-8700
