Default Getting belt walk with ATI 917302 balancer

I did an LS swap in my 94 Camaro. Everything is good except for one thing.

Brought the car back from the tuner and changed the oil only to find the belt walked forward on the p/s and tensioner pulley about 1/2 inch. I am running the OEM belt, everything else on the accessory drive is OEM except the ATI balancer. ATI tells me I should be good, but obviously its not right. Anyone have ideas? I'm going to double check that the balancer didn't loosen during the dyno pulls.

If all of the accessories match then this is not normal.

You can try the idler pulley with a taller lip from a blower car.... thread about it somewhere. Can't remember what they sell it for, Pontiac GXP maybe?

New OEM belt for an LS1 right? Gates or other brand?

Does the balancer line up with the other puleys?
