I have it and love it even after almost two years. When first installed the bike would spin the back tire while accelerating out of twisties up Mt Rose from Reno to Tahoe at Street Vibrations, which was dangerous and embarrasing. I had it re-dyno-tuned and frankly its near perfect. The power comes on even faster. Plus it only operates when I twist the throttle about 3/4 of the way (setting is adjustable). Of course the bike won't go any faster top end. I still get the same mileage as long as I don't twist the throttle too far too often. But when I want to play, its large fun. I recommend it if you can dyno-tune at an approved PowerCommander tuning station.
