BMW could claim, on an in warranty bike that your modification has affected the engine, exhaust, catalytic converter, drivetrain (by adding more power loading), etc., etc., etc. The same could be said for IAT modifiers, Techlustions, and PowerCommanders.

The reality is you're only adding the amount of fuel needed to make your bike run better. In my case with a 9 year-old R1150RT I don't have any concerns at all.
