I currently have the under drive pulley setup installed and seem to be getting a loud squeal from one of the belts...it seems to only happen when the car isnt under load and/or while its cold...in other words it only happens when im not driving it down the road (from what i can tell)...could it be worn belts?...i have no idea when they were last changed...

 

I would change the belts with new ones...I'm guessing you have v-belts and make sure they are tight. Not breaking pullies tight, but tight enough not to squeal. What I've done to minimize squeal is to get a turnbuckle and chain and just keep turning the turnbuckle until its not squealing under any load...
