I found that with standard pipes and a decat, was getting about 87 HP at the wheel on the dyno. After tuning with the PC5 now at 94 HP. Makes quite a difference. Have the next up quickshifter and really enjoy the smooth and fast up shifts. However doesn't really work at low throttle, so not really for cruising around the city unless you keep your revs up.
But based on running a quickshifter for about a week, manual shifts seem to have more lag in throttle response than without a quickshifter. However the shirts using the quickshifter at higher revs is very smooth. So not sure I would recommend this for city riding. Am considering unplugging when not going on longer rides.
