which way to mount balance belt tensioner?

[s1ngletracker]

Ok, I'm an idiot and I took off the balance belt tensioner without noting on the orientation of the tensioner.

I have a 93 tsi awd with a 7 bolt. I had the tensioner mounted with the lip side down, but it was shredding the belt and making noise... I mounted it the other way and it seems to work better, but I can't find any reference saying this is the way it SHOULD go.

I seriously just want to stop taking my timing belt apart. I've been doing it like every other day. Annoying.
