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 FlashCal F5 Calibration Tool Reviews


FlashCal F5 for 2015 Jeep Wrangler Unlimited

Reviewed By Thuy D (TAMPA, FL) Reviewed for a 2015 Jeep Wrangler —3/18/2017 7:40 AM

Worked perfectly to re-calibrate for larger tires as well as disable the TMPS for airing down the tires. Really like the colored screen versus the DIP switches I have had to use in the past with the competitor's calibration tool.
