ECU on its way to Guhl's!

I hope you have better luck than I did with the reflash. I have a K&N filter, TSR air filter cover, gutted stock headers, Oxygen sensor remover, and the reflash. It seems to have picked up a bit of part throttle responsiveness because of the increased ignition advance maybe, but I have to have the engine above 5000 rpms before I can give it half throttle with out it feeling boggy or soft as I wind it up. If I give it full throttle at anything below 6000rpms it holds back or is boggy again big time. I think it was set too rich for my bike as setup now. It feels like I'm riding a 600 supersport bike with a bit more grunt at low end. Not as good as the way it was set up with the stock ECU settings. I'm not happy with it and I guess I'll have to send it back to try some leaner settings at midrange and WOT settings.

When you say gutted stock header, do you mean basically open exhaust? I have an aftermarket exhaust, and if I remove the baffle (I. E., reduce back preassure) I basically lose all low-end torque from below 5-6k, the same as you describe. I remember it was so bad I basically took it out for one ride and then never put took it out again.
