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!

Nice tuner.

Reviewed By Cody H (SODDY DAISY, TN) Reviewed for a 2004 GMC Sierra —10/9/2014 8:48 PM

Bought this tuner to go along with my full exhaust and intake. Made a very noticeable difference in power and the way the truck shifts. No mpg improvement that I've noticed, but not why I bought it. Would definitely recommend on GM trucks. Also allowing for custom tune is nice as well.
