I installed the PC111 USB, and it works great as i mentioned in another thread, I also looked at the QUICK SHIFTER does anyone know what the pros and cons. It makes sence and looks interresting. Is it worth it, i mean as far as by-passing the throttle % and going clutchless look like a good idea. I was reading and it looks like something i might be getting. On the website Welcome to Power Commander III USB Motorcycle Fuel Injection Tuning Module got me thinking.
