Well, Hi! My Oklahoman Brother. I used to work For Matrix when I lived over there. I need some info on your truck? Like Is it a m/t or an Auto? The next thing is, what your cab configuration? Is it a 4x4? Did you have some decent MPGs before you replaced the Cam Position sensor through Ford, when they did their recall? What size tires are you running? and are you prepared to change your driving habits? Let us know and we will steer you in the right direction. you can track your progress through this site Fuelly.com
This is my average city driving MPG

Your driving a truck that weighs about 8500#, it has the aerodynamics of a brick...
About the best you can do is drive it like there is an egg under your foot, keep the RPM's below 2k when ever possible.
Changing the CPS will NOT gain you anything. There is some Perceived issue with the Gray CPS, I have not seen anything worth while that shows it.
Rustin, Why do you prefer SCT? You do understand you can access more parts of the PCM's programing with a chip right?
There is NO reason to use a flash tuner on a 7.3...

Thats about all you can do, check the up pipes for leaks, get some gauges in there to see what your boost and EGT's are doing...
But the best I would expect any Dually to get is about 15mpg... Its heavy, its wide and its got alot of ground contact.
Check the air pressure of your tires, go to MAX rating of the tire and that will help as well.

Here is where we have a difference of opinion. With all due respect to Joe (CSIPSD). He knows his PowerStroke, and has yet to say anything wrong. I did the grey CPS after the Recall. I thought nothing of it. For about 6 months I had issues of fuel economy, and false injector codes. I have been on many forums complaining of this issue. One member on another forum sent me to Clay over at Riff Raff. I bought the black CPS he sells. Replaced the grey one and put it in the glove box. The truck ran like it was supposed to. Starting was not so hard, and my fuel economy went to normal. I will say this not everybody has had this experience, a small minority did not experience any change in the behavior of their Power-plants
Just a difference of opinion Joe. What you, and I do might not work for everybody.
