Last year, I installed a Leo Vince slip-on and plugged the PAIR hose. I then installed a PC-V and the Autotune box that goes with it, using the boss on the Leo Vince for the O2 sensor. I loaded a map for an Arrow slip-on for a starting point, and started riding. Every few days I plugged the laptop in and accepted the offsets the Autotune made into the map, and rode some more. Eventually, the offsets became small, and I'm just allowing the Autotune to make small adjustments now.
I don't have the notchy throttle at low rpms anymore, and the driveability is just about perfect. No popping. Performance is improved a great deal. I'd recommend this to anyone.
