Rough idle

Rough idle
My car is running great with no codes or anything, but I feel like the idle is a bit rough. Specifically on the pulley side of the engine. It tends to be much nosier on that side of the engine and vibrate more. That said, I do have a Vibra Technics passenger side motor mount and a new Lemforder lower mount. Trans mount is stock with 67k on it.
The part that concerns me is that the tensioner is bouncing a lot it seems. The tensioner (Lemforder), idler (Lemforder), and harmonic balancer (ATI) are all new. I just feel like there's too much movement in the belt and it's causing a lot of vibration. When the car idles at 750 RPM it's jumping hard and I can feel it in the car, where if I rev it slightly, say to 900 RPM it gets very smooth.
Anyone seen this before? Any tips? Should I be concerned. I just feel like it can't be good for the life of the tensioner.
Thanks.

It may be the belt is a piece of junk (you know what I mean) There are many sub standard belts out there! Try that first and don't use the same brand.
