# 1 I had the dealer fix a valve cover oil leak with the same mods and they gave me no **** but if the supercharger goes or engine gets dusted they wil blame you!!

#2 Clearance between the pulley and clutch magnet should be at least .020" but just make sure they don't touch both running and not.
Mine did rub so I emailed Code 3 and they sent me some shims.

A tune will help but is not required.

You got one hell of a bang for your buck!!!
