Magna Charger Supercharger Kits Reviews


Best supercharger out there

Reviewed By Jennie C (MANSFIELD, TX) Reviewed for a 2011 GMC Sierra —9/18/2013 8:41 PM

Awesome product . Put this product on my 2011 sierra denali and it's amazing. The horsepower and torque make my truck a force to be scared of for any competitor . My gas mileage was not affected and this vehicle now is the funniest thing to drive I've ever owned. I strongly recommend this to anybody who wants a stock drivable vehicle intell u put the throttle to the floor.

Whipple Supercharger Kits Reviews

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
