My truck is 05" 3/4 ton crews cab LLY. Jody's tune picked me about 4-5 MPG, depending how I drive it though. Picked up a fair amount of power as well! On average gets around 15-16 around town and 22-23 on the HWY if I keep it in the sweet spot around 70-72 mph. As soon as push to 75-80 mileage goes in the toilet. Other than an air filter - that's the only thing I have done.
