Yeah, I got almost identical increases on my Aprilia when I installed slip ons and a canned tune from Factory Pro, and some basic airbox mods. Not the same numbers, mind you, but percentage increases from the factory crank numbers compared to at the wheel afterwards. Bike drivelines are very efficient compared to cars.
