Whats up with Kenne Bell Big Bore kits?

I see that kenne bell has come out with a new series of superchargers, has anyone gotten a 2.1 yet, i know they say thats the replacement for the 1.7, but they have the same power ratings on their graphs, whats the deal, i figured with more displacement should come more power right?

Slightly more power, less heat, and more efficiency at the same boost level. Plus the "opportunity" for more power.
