so for LESS money, i could have had the race ecm and ecm spy to tune to the bike appropriately and theoretically had a better running bike?
Possibly
IS the race ecm "better", like will my bike be "faster"?
Race ECM was designed Specifically for the Factory Buell Race Kit (Buell Race Muffler, K&N Filter, and of course Race ECM).
With the entire Buell Race Kit, YES it would make your bike run faster.
it doesnt matter anyway, because i can turn my factory in to a race right?
Yes you can, ASB and Xopti, both sell Custom(Race) Maps for your ECM.
