There is no way to lean the mixture off other than flashing right?

Well, there is providing you have the right equipment. You can edit your fuel maps using the ECU Editor, the wideband sensor and the data logger. Without it you would be really poking in the dark and could potentially damage the engine. Every motor is unique so even loading the maps from other tuned bikes does not garantee the optimum performance. The best is to take it to the dyno. They usually even give you a copy of your map if you ever change the ECU.
