Usable power for the street?

This is a classic example of knowing what one wants.

Too many think they want the horsepower, when what they really are talking about is the street power.
Yea I made that up to get the point across.
And a dyno can only hint at the torque and power at street rpms.

I've got pretty much that exact motor (the before curve) and I want the after curve. Bad. Motor just feels slow. Fun enough around town when just driving it, but when I get on it (like passing on the highway), just doesn't feel like there is much there. Nice thing is, it shouldn't give up anything down low, but make a bunch more up top. Win-win.
