I never sent any RPM belts with the ACE kit. I do however send them with the Rotrex. Turns out the RPM belts actually have a big variance in length over the standard belts, even if they have the same number/length. On the Rotrex kits the RPM belt on the supercharger will have a ton of clearance and can be placed on without even touching a pulley. The regular 10 rib belt needs to be rolled on and is a challenge. 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.
