Works great on my GMC 6.0

Reviewed By Tim D (Chickamauga, GA) Reviewed for a 2007 GMC Sierra —12/10/2015 6:51 AM

This is my second truck with AFM, but I couldn't tell when the truck went from 8 to 4 cylinders on my previous vehicle. This truck would vibrate and make an annoying noise when switching back and forth . The Range took care of all issues. The truck runs great and my mileage actually went UP about 1 mpg. Not sure how that's possible, but it's the truth. For about half of the price of a tuner, it's a great value as well. I would recommend the Range to anyone with AFM issues.

I noticed the engine opens up now when I want it to. Before the response wasn't there. But it wasn't easy figuring out the shifting configurations. I had to research some forums but there's not much shared about it. I paid $275. Great deal

before i purchased i read the reveiws of all the tuners i could find for my truck. this one seemed to be the one for me. it works. however i havent noticed much of an MPG increase. which is why i bought the tuner. maybe if i could keep mt foot out of it, it will work better.
