I had a Rexxer Tune (similar process to Bren Tuning) on my 2008 1200S a few years back. I told them to tune it for 93 octane fuel, an Akrapovic slip on, an aftermarket air filter and told them about my low speed fueling issue with the bike. Prior to the performance parts and the tune the low speed fuel was "ok" but seemed to be pretty lean. The R1200S was out of warranty.
After the aftermarket parts and the Rexer Tune were installed it was like a different bike. The low speed fueling was much better and the bike was much easier to ride.
In the past I have also had a number of motorcycles tuned with Powercommanders. A number of those bikes were dyno tuned with before and after results. After each tune the driveability, the AFR and power curve were all smoother. I also picked up more horsepower and torque
Since those days in the past I have not felt the need to try and improve the low speed fueling on my water cooled BMWs. It seems to me like the fueling while probably not great is pretty good straight from the factory.
