had mine re-flashed, amazing change!!! under 6k it pulls like a lower gear, adds so much to the performance of the bike,
most days i'm in the twisties in say 4th - od, lower rpms under 6k most all the time, the flash is an amazing change in that range.
Now if your tac is always pointed north this might not do much.
i did the flash after 61k miles, so i for sure know the change is not in my head. (4k miles ridden on it since)
(also flashed for a cs-1 installed at the same time)
great dealer at a great price !!!
