I recently added a BMC air filter and already had a slip on exhaust; so I decided to have my ecu tuned by Rexxer. Therefore I no longer need the boosterplug. Been on the bike for about 1k miles, works great! Does everything just as advertised. Really cures the twitchy throttle. Paid $155 new, asking $110 shipped! (conus)
I will add pics later, but really there's not much to it. Its in perfect condition.
