The Pcv with a proper map will do wonders. I had a generic map on mine and the bike was a complete dog below 5k. After a custom tune it with was a completely different animal.
I also recommend upgrading to a 190/55 rear tire to get more rubber when leaned over. When doing so go +1 on the rear gearing as well.
