I got an iice unused unit from one of your customers Now my temperamental r1100rt is much smoother. Since I do the same commute every day I have a pretty good "test track" that I know very well and how the bike feels and responds. The "raspiness" under acceleration is gone on the low end. The hesitation between 3k and 5k rpm is gone. Between 5k and 7k it feels like a bit healthier. The bike always felt too lean. Now it feels about as good as it could be. The people that say it does nothing perhaps they have not a well calibrated seat of pants. It does what it says it does. Waiting for more products to come.
