Maintenance and Modifications > Boosterplug vs. Accelerator on newer GS (hexhead)
First, I have an '09 GSA, not a cam head. I used the Booster Plug on my machine and it made a noticable difference. Prior to installing it, I had a slight hesitation in throttle response when my wrist felt a bit agressive. The machine also popped while gearing it down. The Booster Plug eliminated these things. In fact, one of the techs at local BMW store commented the other day about how crisp the throttle response is on my bike.
Oh, I had a little hassle with the Booster Plug after it had been on the bike for 2.5 years. I notified Jens and the new unit arrived a few days later. Great customer service!
