Kyle_KleinSS , did the cps that you got from International come in a sealed plastic package or a box? I'm just making sure that you didn't accidentally(someone parts swapping)end up with a cps for a dt466(dark blue)which will retard your timing 2 degrees and kill your fuel mileage.
The so called "new and improved" one that I just bought is dark gray with a bright purple O-Ring. DU-87____F4TZ-12KO73-C.

It came in the box. Very dark grey almost black purple ring. I am hoping that the cps is my issue I guess ill pop my grey one back in and see what happens to my mileage. Idk what else to check?

I may have to put the grey one back in and see if that changes my mileage or not over the black one I put in that I got from Clay. I filled up the other day and it about took my breath away. Has anybody ran the different CPS's for a period of time and recorded any change in mileage?

No I havent. The truck is smooth as butter. If its the harness thats loose causing it to suck fuel wouldnt it run rough?

Also Im in Illinois and using winter blend fuel of course. And I got 315 tires now. I had this problem before the tires so I am gonna rule them out. And the winter blend wouldnt drop me that low would it?

With the gray CPS I was getting 16-17 MPG's at best. When I put in the dark blue, it stayed close to the same, but I only ran it for a few months. The black CPS gives me better mileage, I can get a little over 20 mpg on the highway, and 18 mixed. When I tow (8500#) I get pretty much 10-11 MPG's no matter what CPS I use, but that is most likely caused by my right foot

I am getting just over 11 mpg in the city. Most of my driving is city driving. I am also thinking possibly exhaust leak or maybe the ICP sensor I checked it once and it was oil? I just checked for boost leaks and everything checked out good. Unless 11 mpg is considered good for city driving?

The 1876736c91 is for the 94-96 7.3L engines. It is also sold as Ford P/N F4TZ-12K073-C. Here a year ago or so it was supposed to be the "latest and greatest" one out there. I bought one and ran tests with it along with the OEM black one and the gray one. It did not impress me and has been in the glove-box since.

Same as me I have a very short commute to work as well. I also disconnected the EBPV from the pedestal and it has made a huge difference in drivability in the morning. I am still waiting to see if it will translate into better mpg? I am planning on checking for exhaust leaks this weekend as well.

Mine on a switch no control from the pcm so I wouldnt count on it, diesels use more fuel when cold and dont combust near as good until warmed up. Im starting to think mine/ your problem is just the short commute and most of the driving is done when cold
