Go to conclusion section and you will find the following statement:
"Based on the fueling responses we saw during this testing, I would be very hesitant to run a stock ECM on ANY bike equipped with these exhaust systems. In some cases, the Race ECM provides a decent match to the fueling needs. But in most, a remapping of the ECM would be the best way to assure that the fueling is neither too rich, or worse yet, too lean."
Bottom line, I'd put in the time and tune your ECM. Its better to run too rich then too lean, so I'd put a race map on there if you don't want to tune it.
