You say you polished the stock TB, that is the 112 part. I am assuming you meant the 113 TB was polished in which case if you forced the throttle plate open to get at the inside bore you may have damaged the throttle position sensor.
The 113 tb is completely stock. It’s possible it was forced open before I got my hands on it, as it is a used part. I polished the v6 112 part, which is now back in the car with the stock MAF housing, and the car runs nicely again. I believe the issue was the eBay MAF housing not sealing properly, because the car did not run well with the larger MAF and stock, polished 112 TB. I didn’t have the security torx, so I did the change in stages, and was able to see how the car ran with different combinations of parts:
113 TB+113 MAF housing= Symptoms of a vacuum leak, seemingly decent WOT performance once, slow throttle response.
112 TB (polished) + 113 MAF housing- same as above with sharper throttle response
112 TB (polished) + 112 OEM MAF housing - runs well.
So I think my next step is to give it a shot with a used OEM 113 MAF Housing.
