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 Flashpaq F5 Tuner Reviews


Easy to use!

Reviewed By Steven B (SAINT AUGUSTINE, FL) —6/12/2017 2:28 PM

The unit is easy to use and switch between tunes after initial set up. Only issue I had was during install, the directions stated to turn the key on and not start the engine...it should state to turn the key to run and not start the engine. All in all good product which produces improved performance.
