They share the same engine and the RSV, I had there map in there for a few hours, as my eprom chip was playing up so I tried a friends who had a shiver, power was a little low compared to the RSV, but it was still good. And I am guessing you can shove a remapped Eprom on there. Very easily available, I got mine for £15 off ebay. Made a massive difference.
Obviously depends on air filter and can, as a different map without these may hinder performance.
