Superchips Cortex Programmer Reviews


best increase for performance for the $

Reviewed By Terry S (Rochester, NY) Reviewed for a 2009 Hummer H3 —11/2/2009 11:13 AM

The ease of the installation is hard to believe. Then you start up your car , and away you go. The instant I took off in my hummer I had a huge smile on my face. I then took my daughter for a ride and watched her face as I gave my truck somme juice---and she said " dad what did you do to "Jake" [my trucks name} "? I told her about your programer, she said " AWESOME" !

Superchips tuner

Reviewed By Danny G (farmington, IL) Reviewed for a 2013 GMC Sierra —3/22/2017 3:31 PM

This is my second superchips tuner I have purchased, one for a 2009 Sierra and this one for my 2013 Sierra. Combine this tuner with a good cat back exhaust and cold air intake setup and you can tune your truck to run the way you want. Very happy with the ease of use when connected and making changes. No going to the dealer when installing larger tires to get the speedometer reset.
