ok i got the Pulley Boys Quick Change 2.7 Pulley for my GM supercharger kit.  Is their anything i need to do beside put it on?  Should i get it dyno tuned?  Will the A/F system be fine with the GM charger fuel setup?  Any other worries/recomendations?

If you want to insure you have a good A/F ratio buy a 
Innovate LM-1.  Or another brand of a wideband reader.  That is the only way to know with your performance mods if you are properly tuned.
