If it was my truck , I have a 97 international with n-14 and the new injuectors didn't fix it and the scan from Cummins told you nothing I would have coughed up the $500 and ran it on a Dyno nextChevyCam, Intothesunset and BigJoeTX Thank this. -
Another out of the box thought for you. What if they swapped that from a tractor? The ECM settings would be for a stationary unit and would suck for automotive type driving.
You mentioned you had another N-14 close, you might try swapping the ecm and see if it makes a difference. I’ve seen this a handful of times in mechanical engines where the fuel pumps had to be changed over to a different type of Governor to make the engine run right for the application. -

Have you checked full pressure when has low power. No intake or exhaust restrictions?
