This was (maybe still is) a popular item to remove from the 2.5 Turbo Mopar engines from 89-92. Never knew if the engines blew from the balance shafts or just because the engines were THAT poor.
I know those engines didn't come with knock sensors, so I am sure that removing them was detrimental.
We have knock sensors on the 3800, so if we remove them I suspect the knock sensor will pick up noise caused from their removal, thus you would have more KR. Not a very worthy investment of time and gaskets.
But then how do we set new limits without testing the old ones?
