Reviewer: Terry A (Goodrich, MI)
This is just an awesome disabler (Magic Black Box). It work perfect as stated just plug in and drive. This has made driving my 2013 SS Camaro 6 spd auto works like it should V8 power all the time. If you want better fuel economy just unplug and back to V8-6cyl-4cyl as GM designed. Then plug back in back to cool driving and load exhaust. This it just one of the greatest products I have purchased in some time that really works as advertised great job.
