Supercharger Review

Love the instructions as I am a novice. Magnuson made it super easy for a flawless install. Much easier than trying to do the Edlebrock or other kits I researched.

A very well designed and thought out supercharger kit. Installation instructions are very comprehensive, however makes sure to keep track of which electrical connectors you have been instructed to disconnect as the instructions don't always tell you when to reconnect them potentially leaving the hidden ones disconnected. My biggest issue at the moment is getting the tune installed. If you have Windows 8/8.1 expect headaches with updating the tuner and installing drivers. Update via wifi directly
