I use the ECU for nitrous on rare occasions so I can't use the shifter function. So I use to run Cycletek Air Shifter which worked awesome but I decided to get rid of it for more street riding and road track excursions. So I went with this quickshifter from this place: Dano's Performance as it has it's own kill box.
I have not put it on yet but will let you know how it works once I get it on.
I use an MPS quickshifter it would work great for your bike. you can click the link in my signature to find out all the details. But i did a complete write-up on the install for my cbr...if your interested in the write up just PM me. Good luck with the search, there are plenty of awesome choices out there
