08 gt500 belt squealing

[Skibs]

I have a 2.6 metco upper pulley and metco idler pulley and the innovative west 10% lower pulley. I can't figure out this problem my squealing belt. I have adjusted the supercharger pulley forwards and backwards to see if that helps, but no luck. I have replaced the belt and it stops for about 300-400 miles then comes back. It sounds like its coming from the supercharger pulley. Currently Im using the gates green belt. This car isn't my daily driver so when I drive it I am driving it pretty hard normally. Wouldn't think that would have anything to do with it. I'm looking for suggestions. Has anyone had any problems with the metco supercharger pulley before? The belt rides straight and as can be and looks straight as I can tell with my eyes. I appreciate the help.
