The 4 pulleys i compared it to were 3 factory SC pulleys and 1 of Rudy's "Karmen" pulleys (these were all essentially the same in this spec).

Now, I don't know if the deviation I observed (and measured) in this Eurocharged pulley is representive of the spec they are working with .... but it might explain your issue.

This is interesting, the pitch of the ribs on the belt are about .140", so if the ribs are out .085 then the tendency of the belt to want to jump is very strong. At the very least the ribs would get very hot and get destroyed.
It is critical that the back of the pulley bearing and the ribs keep the same dimensional relationship as the OEM pulley.

When copying the OEM pulley this relationship is vital.

Of course adding shims incorrectly will give the same result.
