The easiest thing to do with a tuner/programmer is increase the boost of your turbo or turbos. Increasing the boost of a forced induction engine can increase your efficiency and power.
By the way, a lot of guys are showing highway mileage being so high. In town you'll still get crappy mileage. But on the highway when you're in overdrive and you're at a steady low rpm, your turbos give your engine much more efficiency.
I would suggest a Banks tuner. My buddy has one on his old F350 with the old international diesel. It's putting down around 1200 foot pounds of torque.

An easy canned tune will net you 120HP on a 6.7 Powerstroke. This is with no deletes and factory DPF, etc. Remove the filters and then the fun really begins.

Not really...adding fuel is what increases boost...
Optimal boost cruising on interstate at 70 is no more than 6#
It's different on different trucks based on gearing, but you want that number as low as possible when cruising the highway...that and the lowest rpms and egt's

Increasing boost does the opposite to MPG. The more boost used, the more fuel it needs to make up for the added air induction. The highway modes do not increase boost, they change fuel/ignition timing maps to be more efficient. All turbo motors whether they are diesel or gas run very very rich from the factory to help prevent detonation. Smooth those maps out and you instantly have way better MPG.
