The power with a reasonably small turbo is very progressive and does not get twitchy mid corner, it still depends on how far you open the throttle as to how much power you get. Mine on a cold day when the carburation was better would make boost from 4000 to 11000 revs giving 7000rpm of boost to play with

The small turbo does restrict top end power, but there is a limit to what you can realistcally use on a road bike. 200bhp at the wheel feels fast enough for me.
