Also, does anyone know of a programmer or module that will give me better mileage and not leave a footprint that might void the warranty? Thanks in advance. The logger.

I know you are working on it, but I would find the problem before adding the tuner. With that low of fuel economy, there is something wrong. Are you sure they hooked everything back up after the turbo and EGR work?
You could always try the PCM re-learn ....
PCM Relearn Stragey:
To do this drive the truck for 15 minutes and get it to operating temp. Then turn the truck off and disconnect both batteries for at least 20 seconds. Then reconnect the batteries. Now cycle the glow plugs on then off twice. Now start the truck. Do not move the truck now, Let it idle for at least 7 minutes. During this time you will hear the exhaust note change, this is the truck learning a strategy. Make sure the truck is hot, if it isn't it will not work right. Then drive it - vary the driving conditions for 30 minutes.
