Theres like over an inch of difference.

If you run the setup I sent with the ACE kit then the idler should be on the bottom with the K071065.

If your shop changed that and moved the idler to the top then your belt should be the K071045

I am unsure what size your silver pulley is. I am guessing they also changed this and thats why your boost is so low. The ACE kit will consistently make 14-15psi with the setup I send. You should go measure that pulley.
I also plan on getting the K071065 belt and put the idler back to the bottom position.
