Fuel mileage

wanted to buy a new truck this year but I remodeled the house instead. So I decided to play with my 99 SD it only has 60,000 mile on it and still in exel shape
I started out with the K&N filter kit then tried to install a diablo preditor tune but it would not take tried 4 times with 3 differant units. ended up installing a hypertech 3, then installed a dynomax exhaust 3"in dual 2 1/2" out with a magnaflow high flow converter.
Gas mileage went from 13.5 to 12 and tried to keep my foot out of it.much more power.
anybody out threr have any ideas to help fuel economy?

I know you've heard this before, if ya want better fuel mileage, leave it parked or trade it on a car. I drive mine 100 miles a day round trip to work and never worry about the mileage. You couldn't give me an econobox to drive each day.

If you want good fuel economy, keep the engine at 1,500 rpms or less.
