Superchips VIVID Performance Tuner Reviews

2008 Silverado Vivid Tuner

Reviewed By Bryan I (Carlsbad, CA) Reviewed for a 2008 Chevy Silverado —4/5/2012 8:51 PM

I have a 2008 Chevy Silverado Crew Cab with 33" Nitto Mud Terrains on 20" XD Monster series wheels. I have added a K&N Gen 2 Cold Air Intake, Airraid Throttle Body Spacer, JBA Headers, a Magnaflow exhaust with Stainless Custom 4" pipes that blow out just before my rear tires and Now have recently just added the VIVID Superchips Tuner to the mix. I have always only ran 91 octane fuel and now still continue to run 91 with the tuner custom programmed for high performance at all times. I can honestly say my truck is faster and louder than ANY other 1500 I have come across. The paper work claims I have added over 80 HP to the rear wheels as well as 70 ft lbs of torque. I'd say it's close to that. The Tuner helped out deffinently but it's not a magic super chip... U need to go all out and let your truck breathe and exhale if you want performance.
