I would suspect rail press Gauge if derate or injector maybe?
Just ideas there.

Not derate I'm positive of that, it pulls fine until I start pulling some hills then fall on its face. I have to drop some times down to 10th in PA and WV pulling tanker, 18sp 550 hp 3.42 rears

I would definitely try another fuel pressure sensor or press relief valve . Or try that hill again and monitor insite at the same time to try and pinpoint problem.
