You have a huge engine, a gas guzzler. You may need to change to a more modern and efficient vehicle - a smaller engine probably. Or a diesel engine???

they sell a PLUG IN - Performance Gas Saver Tuner Chip Upgrade 2000-2015 (ebay) keeping air filter clean and some fuel additives help. but other than that you would have to change axle gears or you could up the tire size 1 size and lay off pedal will help. try driving and not letting it shift over 2500 rpms. you will see a difference
