I installed this at 38,000 miles on my 2013 GMC Sierra 1500 Crew Cab 4x4 with the 5.3 Liter. I can't say the fuel mileage is better in town, seems to be little or no change but on the highway, I am getting approximately 1 to 1.5 MPG more. I can say with 100% certainty that the Throttle response has improved. I can only attribute this to the increase of air flow into the combustion chamber.

So first of all let me start by saying this thing does have a whistle noise even though it says its quiet. I do have a aftermarket intake and I'm not sure whether it makes it whistle more because of all the air coming in faster. Also I had to cut some plastic to make it fit because of aftermarket intake. Now for the mpg/hp/tq gains as far as the mpg I'm not too sure on that but I do have better throttle response and my truck gets going better than usual my truck does feel like it has more power.
