Question: Mitsu Raider Poor gas Mileage

I love this truck! however, I have noticed that it averages about 10 MPG's sometimes less. it shoul be getting around 16 in city 22 in Hwy.
when I bought it (used) they had to replace the fuel pump inside the gas tank, and we noticed that the MPG's dropped. we have taken it to the Mitsu dealer several times, had the computer read everything within the guidelines, yet the car sucks it up. I have not done a tune up yet, I did get new tires, and put sea foam to clean it out in two seperate instances, nothing seems to work. Wife is frustrated wants me to consider changing trucks. I still believe in the tuck, it runs great. anyone have any suggestions?
