2009 GSX-R1000 restriction
At the moment, my bike has a custom AF map. Out of curiosity, though, aside from the top speed being limited and all the other stuff, how restricted is this bike in terms of horsepower numbers? I've read from multiple sources that the secondary throttle valves close a bit and that the ignition timing is retarded (for the purpose of passing emissions requirements) at the top end at the lower gears (or maybe even the upper gears?), thus some of the potential horsepower is corked up. Also, for those of you who have flashed your ECU, what were the results?
