Tuneboy, Rapidbike or Rexxer
Did anyone here have an experience with Tuneboy, Rapidbike or Rexxer? I just want to know the difference. I've heard that the majority of bikers use Rexxxer for adjusting the fuelling map of a bike, however, there are a lot of good reviews about Tuneboy and Rapidbike too. I'd really appreciate your help in this matter.
