Those look sort of like the ones I have on my 01 RS.
of course my harness is setup to deal with the TPS (Orange Plug) so I don't use the tool.
1200 GBP is a little expensive (what, that's over $2000.00), but I guess since they are setup for running on an earlier mode bike (pre 2001) with the proper setting tool, I guess it's not that bad.
The big question is will it give you that much more performance for that kind of investment?
