An update:

When I got my tune, Jerry at Eurocharged listened to the noise I was trying to describe to all of you. I had no shims installed, and he told me that it was rubbing slightly on the backplate and it wouldn't hurt anything. I didn't like the constant grind noise, so I decided to go for round 2 today and add a big shim to the mix (thanks to billvp).

My clearances are now greater than .32.

Before I added the shim, the car, from a COLD start had the grinding noise present. Just a constant drone of metal rubbing on metal.

After I added the shim, the car, from a COLD start did NOT have this grinding noise anymore, but DID have an intermittant (we'll say twice a second) noise for about 2 minutes after starting. I can't even describe this noise, though it did not sound like grinding. After the car warmed up, I took it for a spin. When I parked it, I heard the GRINDING noise again, but not the intermittant noise I was just describing.

Seems I can't win here. When the car is cold, I don't hear grinding but I hear a strange rut rut rut rut noise for a few minutes. When the car is warm, I dont hear the strange noise, but I hear the metal grinding.
