So what can I say. I made some changes In my bike before I have installed RB. First I changed slipon to SCProject and air filter to Pipercross. After that modifications I felt in some middle range power drop. To some range bike in full throttle behave normal, than drop power and after getting some rpm again get normal power. After installing RB module with o2 narrow sensor, auto adaptive function create own map and now my bike behave in full rpm range normal. My positive felling is that bike get more power in down and mid rpm range. Of course fuel consumption increased about 1-1,5l per 100km more. To get right information from narrow band I made pair mode
