What do bowl stuffers do? I have my bowl off and was wondering if it would be worth $159 to add a stuffer.

a stuffer closes the gap between the rear of the impeller and the bowl. it keeps the water exiting the impeller from swirling around in the dead area between the bowl exit passages and the center of the impeller. its worth the cash in my opinion. if you have an American Turbine impeller, it has a flange already that fits into AT bowls so the stuffer is not necessary.
