I fitted one to mine, it works a treat, smooths out the lean parts of the rev range. I like the fact that as/when I change things like exhaust/air filter I can simply plug the laptop in and upload the new map for the new set up. Also has a map for the standard set up of course. Also removed the Lamba sensors and installed blanking plugs in their place as these are no longer needed with the PCv installed.
Plug and play as well so easy to remove when/if you trade in for a new bike.
