Ditto......I had mine done. I didn't have any real issue with it pre flash, apart fom I prefered to ride it in B mode. Now I am happy in STD. Very low revs STD now like B, higher revs like it was pre flash. A small, but welcome improvement for me.
Exactly same for me...Had mine done as it was free. Does what it says on the tin so can hardly be called shit. Not a performance upgrade at all and not meant to be. Horses for courses. I now find it much easier to ride quicker all the time.
