I've had this installed for a couple weeks now, and as soon as I drove my truck afterwards I noticed a difference. Better throttle response, more power, my truck has really opened up now. As far as gas mileage I'm not sure, since I installed this with the Spectre Throttle Body Spacer as well, though it definitely didn't make it worse. Truck also shifts more smoothly, especially on the highway, gives the truck a nice growl. Installation took me maybe an hour, anyone can do it.
