Range AFM works

Reviewed By Delvin C (UNION, WV) Reviewed for a 2007 GMC Sierra —11/21/2014 9:32 AM

I have only used it for about a week now, but so far it has worked great. The truck no longer drops down to four cylinders which is great. Purchased this item to see if it will improve or stop my oil consumption. I will try to update later with my results. Great product that does what it says it will.

Reviewed By Guy S (Sneads Ferry, NC) Reviewed for a 2011 GMC Sierra —11/7/2014 9:02 AM

I have a GMC Sierra, 2011 5.3L vehicle... This item roughly increased my MPG from 17 to 19.5 for both highway and city use. Now I was really concervative with my driving, if your punching the gas pedal your not going to get close to that. The system did change the shifting of my vehicle, I notice an improvement of shifting and responsiveness, the only problem I had with this was a faulty cable upon purchase. I called and a replacement was sent to me automatically free of charge! Good service!

Awesome product

Reviewed By Steven G (COCOA, FL) Reviewed for a 2003 GMC Sierra —10/14/2014 3:55 AM

Although smaller than I expected (the pictures make it look way bigger than it actually is) I really like this monitor. It is totally customizable. From the number of gauges to the background. Everything can be changed to the way you want it.
