Here's a link to the dyno charts of my bike with a Brock's performance exhaust, MNNTHBX Intake & Bazzaz Fuel Controller.hi VersysRider
This is extremely interesting. If I can get the Z to do this them I'm sold. Do you have more details? Either PM me or point me to a URL if you don't mind.
I weight 185 lbs and the bike maintains speeds above 55 mph 98% of the time. A very long steep hill may drop it below 55 mph, but it's rare.
It hasn't been tested yet (at least by myself), but the power commander fuel controller should give more horsepower. If I were to build the bike today I would go with the power commander as it has many more options such as timing advance (could be good for an extra 1 hp).
