Hi Robert
Ya it is there to help improve economy when you dont need the extra power, I find it also takes a bit of the bark from intake noise away as well. My personal experience is that it did not noticable improve my fuel economy, so essentially it was just killing my extra power without any advantages. My buddy gets better economy when he puts it in so maybe its just this motor? The only reason I would run it is if I was not able to beat the noise limit, its an easy way to kill some rpm and quiet down the setup. |
