Not driven it in anger yet as I only went for an "installation" lap, but I'm not expecting a noticeable gain from what I've done today, however from the standard throttle body to the ported one I now run there is a difference yes. Better and quicker response, and it sees to pull a bit harder mid-top end. It feels like it revs a bit more freely too.
Will organize another dyno day at JKM later on this year and let's see if I can crack the 170 mark.
