Crammer30 here, hello. I have purchased an 03 Tundra Sportside from a local dealership. I am a loyal Toyota driver and love my new ride. I know I will use this site wisely, and for the moment I need one question asked. Has anyone had any luck with increasing the fuel mileage in the 4.7L V8? The price of gas is what it is, I am just looking to get a little extra from those gallons! Any assistance is appreciated!
