Haha, yes it does. Though there are perks to this, in that it's easier on things like the clutch. I've been fine on the stock clutch; no slippage so far. When I replace the dual mass flywheel with a single mass, I'll be able to go with a sprung hub organic clutch rather than Kevlar. The stock flywheel is considered a wear item, and I'm fairly certain that it's out of spec at this mileage (129k miles).

As far as the power ratings, I'm not sure. I have headers, Y-pipe, and a race muffler. How does each effects a change in horsepower? It's anyone's guess, but I'd lean towards 15 whp from the Supersprint pieces, based on E46 dynos.

I think there's power to be had in the midrange. AFR at 10.3:1 is way too rich. I have the CEL to prove it. I'll ask VF what they can do.
