Are you talking about an underDRIVE pulley? It's smaller than stock, so it drives all your accessories at a little slower speed. Then those accessories take a little less HP away from the engine.

The accessory drives are made so that they work normal at idle. With an underdrive pulley you may notice a bit less boost to the power steering at idle, a bit less power from the alternator at idle, etc. If you spend all your time driving & not idling, maybe that's OK.
