But it's not slipping, rattling and it's boosting as expected. After changing it once it really is a 15 minute job swapping back to stock. My stock pulley had 45 mm of clearance to the clutch and the Code 3 has a bit more. The instructions say it should be around 20 mm. I don't know where that number came from. Also the tensioner is not a T11. Its a T10. So ignore the instructions. And for Pete's sake, get the proper tool to hold the pulley to get the bolt loose. I have a feeling that some have cranked so hard on the snout of the supercharger following the removal instructions that they've damaged it. The pulley works, the quality control is suspect and the instructions are dangerous. IMO. (bonafide Code 3 first hand owner and user)
