Blower belt slipping?

If you know a stock 4.6, you know that with an automatic the 1-2 shift often squeals the belt, one of the belts, not sure which, but one of them squeals.

With that sound in mind and knowing its a manual 93 SC, under hard load 2-3-4gears I'm hearing that squealing sound under the hood around 4k.

Setup is a 10% Alum ESM OD pulley and a Napa 08030 Belt. I'm noticing for the first time also, a build up of what looks and feels like small rubber shavings as if the belt was spinning on the pulley.

Any answers/thoughts and that is the proper size belt correct?
