Been chasing this for months
I've got a 2000 F250 7.3 with 308k miles. I have this annoying surging with light but steady throttle from 10mph-60mph. Once as high way speeds it goes away. It doesn't always happen either. Some days there's no surging other says it's all the time under 60mph.
In the last few years I've replaced the following:
InjectorsIPRICPCPSBatteriesFuel bowl o-ringsFuel linesHigh pressure oil linesFuel filter every other oil changeCharge pipe bootsDown pipe and exhaust.
I've also been running a "street" tune off of the SCT X4 tuner. I recently removed it as I thought it might be a fueling issues..

Have you ever cleaned out your Exhaust Back Pressure Sensor and Tube?
Welcome to guzzle's Exhaust Backpressure Sensor Cleaning Maintenance Web Page
Also look at you ICP (Injector Control Pressure sensor. Is there oil leaking out of the connection? Change it. Unplug the ICP, does the truck run better? Test drive unplugged?
There is a 1999- 2003 7.3 Diesel section, post there for more suggestions.

I have not I'll give that a go. I replaced the ICP back in August but I'll give it another look. Ive only used motorcraft replacements as I've heard these truck need those compared to other brands.
Thank you 👍

Just saw this post. My experience might be a longshot for you, but here goes:
My '01 (gas V10) came from the factory with a very slight surge at exactly 70 mph. My dealer contacted Ford for assistance as they had no information/experience with the problem. They were told the ABS module was not communicating with the PCM correctly and to replace the ABS module. When they did the surge went away.
