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


Superchips FlashCal F5

Reviewed By Kade S (WICHITA, KS) Reviewed for a 2011 Jeep Wrangler —7/26/2017 8:18 AM

I bought it to calibrate the speedometer after getting bigger tires and changing gear sets in my jeep. It worked flawlessly and it took only a few minutes to use. The screen is very useful and the tool is straight forward and easy to use. It can reset and check engine light codes and many other things. I would definitely recommend this product to others.

Superchips Flashpaq F5 Tuner Reviews


2014 F150 FX4

Reviewed By Lee C (Augusta, KS) Reviewed for a 2014 Ford F-150 —7/24/2017 5:30 PM

I have had the tuner now for a couple weeks and it has impressed me so far. I have only used it on the 87 octane and I'd just Ed for my bigger tires, but it has gave me better throttle response, power, and increased my gas by 2 mores mpg. I plan on running 91 octane and using the tune for it in a couple weeks and hope it does even more.
