The pulley saver kit is designed for the crank pulley replacements. Since this is a supercharger pulley, you don't need the pulley saver kit.
However: some have installed the PSK with a Code3 pulley simply because the design of the PSK gives about 10% more wrap around the supercharger pulley, thus giving the belt more grip and should have less slippage. I've been considering doing this myself. If I get my pulley machined down to 63mm, I will definitely do this as you'll need the extra grip.
