I have a 04 cbr 600 f4i with a jardine rt-1 slip on, and I am looking at getting the power commander. I have read that the only large gains you will see would be at ~40% throttle(off the pc website). Has anyone had their bike dynoed before and after the power commander to see where the gains are found, and how much power to expect? Also is there enough of a difference to justify the $270 for the custom tune over the downloadable files off of the pc website?
