Boost your diesel truck

I drive to work in a hybrid car which gets 45-50 miles per gallon depending on how fast I drive. It has very little horsepower (94), so it doesn't do well up a grade and it certainly wouldn't be useful for hauling stuff. Many of the people I see on the road drive diesel trucks, big ones. Most of these are used for work or for hauling things like trailers and carrying dirt bikes. They have power but the diesel performance may not be the best. What most of those people driving trucks don't know is that by using a tuner or chip on a diesel, you can boost performance and improve gas mileage! That's a nice combination. If you could add 100-300 horsepower and still get 20-25 miles per gallon, I think you'd give it a shot.
