Review on TECHNOLOGY AFM DFM DISABLER COMPATIBLE MOTORS by Ernest Duckett

I have run this unit on my 2011 Chevrolet Silverado and it is amazing! It was very easy to install and I'm leaving mine on! I'm just waiting to move until the light is constant. I've also noticed that my gas mileage has increased! I think it's my driving style and the engine shouldn't think so much! I highly recommend this product as this $200 purchase will definitely save your engine!
