Easy install and start up

Reviewed By Darrel H (PASO ROBLES, CA) Reviewed for a 1999 GMC Suburban —8/22/2014 5:45 AM

It was as advertised. Easy to hook up and so far works perfect. I was able to do a milage tune , then a performance tune and could feel the difference. Also cleared an engine code. Excellent piece of equipment.

very easy and very fast

Reviewed By curtis p (newark, OH) —10/29/2014 11:12 AM

The cortex is a lot easier to use than expected, menus are easy to understand. Makes a world of difference on performance mode with 91 octane.
