I disabled mine on my 2010 600 and removed the servo. There was very little difference in performance and no down side I was aware of. It was an emissions thing I think but Suzuki claimed better low end performance. Like I said, I didn't notice a difference either way - aside from maybe a slightly lower sound at idle.
