Not exactly. Look what happens after 6K rpm.

If the milage on the first two is true, than I think they should get better numbers once the car is broken in. I've seen stock S dyno anywhere between 190 to 210 at the wheel on S2Ki.com.

That tq curve is nice, but it's so low

I rode in an S2k and it was nice above 6k, but omfg was it a dog while not in VTEC. Not fun at all, imo.

based on those dynos it looks like it. The S2K isn't producing the claimed 240 to the crank.
