| Robo,
Not got a 999r (only got the motor but with the out of date bodywork!) myself but Chillo has, speaking to him a few days ago he was looking for a full 57mm system, maybe because of the same problem?
Loads of people swear by the power commander for sorting this sort of problem out.
The ecu's only have stickers on em to identify em. If mine are anything to go peel it off and there's another underneath for an older model!!
