This means that you have not adjusted the front-mounted M5 bolts to balance the belt tension properly. BFI can be a bit more challenging to install correctly than the stock front idlers, because it does require that you get this belt-tension balancing correct.

I also would suggest using a small bit of loctite on the inside threads of the M5 hex nuts in the back of the carrier. This will prevent the M5 bolts from loosening over time.
