+1 to what was said above. My RB R module has totally changed my bike. Its so much smoother.
As a note only the Racing module has the ignition & fuel mapping. The Evo has only fuel. Each cylinder is auto tuned for fuel (only) using the factory O2 sensors.
Its a pretty clever system, well engineered (coming from a guy who's been an automation/process engineer for the last 20 years), and is very straightforward to install. There are several other tuning options out there. None of which I have tried first hand but, for me, the RB works and I have no plans on changing.
