I know how frustrating things like that can be - when they just won't fly no matter what you try. But the satisifaction of finally solving it is inversely proportionate to the frustration experienced.

Did you ever disable the O2 sensors like Davo said - apparently it's an essential step with AI removal on an EFI bike? Of course you need Tuneboy to do the disabling - so that's more $$$. But the upside is being able do your own tuning and diagnostics.
