there is no adjustment on the belt. It's just spring tension from the tensioner.

My belt seems loose as i can turn it.. I have a 15% pulley and ATI super damper.
Also the belt squeaks when its cold or the ac is turned on...
Followed by a few idle drops and the dreaded p1688 engine code

Assuming you're running the proper belt, I would replace the tensioner.

Either the belt is improperly sized or stretched, the tensioner isn't keeping tension, or the SC pulley is slipping on the shaft.
