You want to increase timing and increase your boost pressure. More fuel wont hurt economy but your foot on the pedal can. Get a chip that does timing and fuel, then put a boost elbow on your turbo. EGT and Boost gauges first!

Just installed a superchip programmer, it helped mileage and low end torque. Got it used for cheap.
