I think if you look down the list of names here, everyone has seen this one. The cure for me was a PowerCommander II.
 
SPeaking of the PCII,

Is it me or is the PCII documentation very lacking. They really don't exlpain what the four table really mean (it can be deduced). They give no suggestions on where to start making maps or how to tune using the PCII. It is a plot to get everyone to go to dynojet tuning centers. Thats really great if you have someone that is a busa specialist nearby but some of us dont have that. They are hacks that want to charge by the hour and then don't know any more than I do.

Example, how much can timing be increased in the map? They don't even give instructions on how too tune the PCII using an older dynojet dyno (tons of them here and no newer ones). What type of interpolation does the PCII do when say i set +10% fuel at 4000 and +20% at 5000. At 4500 is is +15%? Is it linera. Non-linear. Who knows?

On the bright side, the PCII really seems to have made the bike feel peppy and much better driveabilty.
