Superchips Cortex Programmer Reviews


Great Product

Reviewed By John C (Stamford, CT) Reviewed for a 2004 GMC Yukon XL —6/19/2012 9:49 PM

I own a 2004 Yukon XL Denali and initially it could not communicate with the car; however, after 5 minutes on the phone with a Superchip representative I found out what fuses to pull and easily tuned my truck. It is now running tip-top shape in performance mode and in gas saver mode, responding beautifully with 3mpg increases. Thanks AutoAnything!

Superchips Flashpaq F5 Tuner Reviews


Works great

Reviewed By Eric I (Spokane, WA) Reviewed for a 2006 Chevy Avalanche —7/13/2016 7:37 AM

After receiving the tuner, I updated through "ignition". Plugged in to my port, and could only get 12% download from stock settings. Called Superchips, got 5 more updates, had to unplug 2 radio fuses,and worked great. 3 to 4 mpg better on economy setting without losing power. Am going to try towing mode, and hope for good results as well. Good product, very good customer support!
