Range Technology RA003R AFM/DFM Disabler-Red

I cannot say enough about Real Truck, they were quick to resolve an issue that I had an immediately sent out another replacement before receiving their return, I highly recommend this company for their prompt response and will continue to do business with them

First time buyer of a product like this . Website excellent I called to place order even on a Sunday and had special shipping request as I was in Canada. The customer service on a Sunday was excellent. Placed order and everything went really exceptional . Got product read instructions , plugged into my truck and instantly working . Super happy with my purchase Great co to buy from I did use Fishisfast to be my freight forwarder to get package to Canada But that was easy as well Thanks from Dean in Canada

Plug it in, give it 10 seconds and drive. Say bye to the annoying V4 and AFM, say bye to the exhaust squeak. Don't overthink it. $250 bucks to make your truck feel like a truck. On command power, shifts smoother, must have for the AFM year GM's.

When I first bought my Silverado I didn't know about the fuel management system. I bought mine used and noticed during my test drive it seemed a little wimpy. I saw this device on the website and noticed the difference the first time I used it. Worth the purchase, unless you want that extra fuel economy...boring :)

Believe or not, this device will save you fuel. With my aftermarket wheels and tires, I was averaging 13-15mpgs, now I'm getting 16-17mpgs. Yeah that's not a huge improvement, but something is better than nothing. Also, when I step into it, I notice there's not as much hesitation. Money well spent in my opinion.
