Supercharger Upgraded 207MM Pulley Belt Squeal

I recently installed a JHM 207mm lower pulley, with ARP crank bolts and I have been running into a slip issue. Before this I had a ECS 207mm which I thought was causing the issue but it doesn't seem to be. I replaced the tensioner and idler pulley when I installed the ECS pulley about a month ago. I have a Bando 7PK1360 belt currently installed. Anyone else run into an issue like this? My only guess is maybe that the new OEM tensioner is bad. Any help is greatly appreciated.
