The HP4 is going to pull more on the dyno than a S1000RR, due to the wheels being lighter and the exhaust giving it a few in midrange. I would guess we'll see a few more on top due to the lighter wheels.
btw H2 - I know of more than a few guys that have installed a full system and not bothered with any fuel management changes. The bikes run fine, maybe not as well as they could with a custom map on a PCV, but well enough for the owners to be satisfied. Our local dealer even endorses this activity.
