Jeffo’s maps perform outstanding on my 09 600rr. He worked with me through the whole process of tuning the PC5 fuel map and other adjustments adjustments in the few places required based on my riding style (I tend to sit a little higher in the RPM range than some people). Even more important than the linear accell. is the fact that with this map my throttle response is greatly improved. I'd recommend Jeffo to anyone. Definitely worth the money. His willingness to work with you to tune the map to you is outstanding.
