My 99 1150 GS just past 50k miles and thinking of spending a few £ on her i.e. my summer holiday that didn't happen money. Put a Remus and Y-piece on a few years ago and thinking of putting Power Commander on. Been reading a bit and seem Power Commander with Wide Band O2 sensor is best to go with. First problem is I can't find the 1150GS on Dynojet site and then some posts say that the Wide Band sensor comes with the Power Commander III but not sure if there is two version of the PC III i.e. one with and one without as can only find images of the PC III on it's own.
