The trick to fuel economy is the air to fuel ratio. Old style carburators were very effective at this, as they came in models from a single barrell fuel saver, to duel 4-barrells that could snap a driveshaft as soon as move the vehicle. The new ECU chips are nice, but they need to be used to their full advantage,and constantly tune themselves for the best fuel economy. Larger ranges on transmissions also help, if you can keep the RPM's low, then naturally you get better fuel mileage. When you go to putting out 200 horsepower and not needing but 50 to keep the truck moving, you're wasting gas. Auto makers need to rethink the whole point of chips, and develop a system to track and adjust the a/f ratio in addition to keeping your car at a perfect 70 degrees, giving you directions, and playin music at the sound of your voice.
