I like this programmer a lot. Could see the difference in power on my Sierra. Would recommend to friends and family.

At first I wasn't sure if it really was working cause I couldn't really see big changes but after about a month I noticed the mpg gains. The power increase was quite amazing too. I feel this is a great product and as they say" you get what you pay for ". Already thinking about upgrading to the IQ.
