How can you tell the erratic variation?
Most of the Ford temp gauges are like dead stick when at temp and its hard to see the needle ever move once warmed up.

Many if us 7.3L owners who have added such things as the 203 T-stat which I did with the first run of them offered by Bob Riley have added "REAL GAGES" such as trans temp, pyro, boost and coolant temp. I have all these with both pre and post turbo pyros. I even have air intake and pre pump fuel vacuum gages to monitor the aftermarket filters I have on those two systems.

Yeah my 2000 7.3 has boost pyro and trans. I would love an aftermarket coolant gauge, but nowhere to put it.
My Ultragauge reads all the other stuff including pre and post turbo intake air temp, oil temp, etc.
Its too bad Ford did not include reporting coolant temps to the computer. No way to read coolant temps with an OBDII scanner.

My gauge moves throughout the "NORMAL" range when the truck is running. Can't speak for other vehicles, but the 7.3's of my era will move based upon actual temp. Not that you know what the temp is, but you can tell when it's hotter or cooler. The oil pressure gauge is a "dead stick" as you call it. Once it reaches the "set" oil pressure, it doesn't move. And I also have A/E ScanTool which will read all these paramaters as well.

C'mon man... You didn't check with your sources on this one. :W

Dang, 6 MPG!

LOL, wow, maybe Ford should have done this mod with their 6.4. Just think Troy, they went with a chin spoiler and only picked up a .25 MPG. They could have went with a stat and picked up, what; 3 MPG on the 6.4?

Silly manufactures!! :R

Remember, that is NOT on a FORD 7.3. That is on a VM Motori 2.8l. Either way, I was shocked at the difference, also. Lesson learned, replace your bad thermostat on a diesel.

The 6.4 has trouble just making the rubber stay on the thermostats!

What ChooChooMan74 said. 203° stat for the 7.3 Ford is a common mod.
