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.

works nice!

Reviewed By craig m (DEMOTTE, IN) —7/27/2015 3:38 PM

Only reason I'm rating 4 out of 5 stars is had a little difficulty trying to register the intune had to get ahold of customer service etc. Other than that great product big gains better fuel economy better all around on my 2006 300c srt8
