dealer to replace idle pulley?

How does this (if any) interfere with the Renntech pulley? I dont think it does, but just wanting to make sure. Think he might have also called it the belt tensioner. There is a sort of "whining" noise from the engine bay which is not associated with the supercharger, but is louder when first started up. It diminishes a little once the engine is warmed up but the noise continues and is rpm dependent (increases or decreases with rpm).
