This little device saved my truck. I was COMPLETELY dissatisfied with the easy the truck ran when the AFM system kicked in. Now, I feel like I'm actually driving a TRUCK!!! As far as gas mileage is concerned, I didn't buy a V8 truck to get good gas mileage, so not worried about that. I will say, though, I haven't noticed much of a decrease.
