I've already gotten a EC tune with the NW CAI. I'm going to install the 65mm pulley. Can I drive it before the re-tune or would it be best to wait? I don't want to mess anything up with it burning too lean.

 

You can drive it just don't do wot runs. You will be fine.

 

Any tips on how to stop the SC from turning to get the pulley bolt out? A leverage wrench and rubber pad isn't working.

 

I tried to follow the instructions and scared my self. Just go down to the nearest hardware store and buy a strap wrench. Cheap, easy to use and you won't run the risk of bending the supercharger snout. BTW, I was using my 65mm pulley for over a year without a tune. The stock programing is real rich. Since your already tuned that may not be the case. Better safe than sorry.

Yeah les he mentioned being tuned already. So they may have leaned him back some. The strap wrench is the safest method.

 

Ok, so I got it installed and now there a small amount of oil coming out from between the clutch plate and SC.

When I installed the new pulley, I removed all the stock shims and it is still 2mm (not the recommended 0.2mm) from the SC.

At first I used a new bolt from Needswings, but noticed it is solid, so I reinstalled the factory hollow bolt. The belt moves back and forth a little while running.

I'll call EC when they are open again. Any ideas on why it wouldn't seat close enough?
