Sounds like a good deal Scott, but not much use to me in the UK unfortunately. Like bobs and ben47 I'd be very interested to see some graphs. 20hp gain (according to the Upsolute website) seems a bit optimistic to me by just optimizing the fuelling/ignition maps. But if you can prove me wrong then I might follow this up through the two UK distributors, although their websites do not list a Crossfire application.
