Hpfp question

I rebuilt my engine last year, put in a new/reman pump from ford at the same time. My question is, with converter locked at say 60 mph, I roll into the throttle keeping the converter locked, rail pressure will only come up to 20k - 22k as rpms increase. Is that normal because of the lower rpms or is my pump going out already? With the converter unlocked, rail pressure will hold at 24k-25k, when getting on it.
Factory nozzles for now. Airdog 4g set to 10psi and elite fuel bowl ****** regulator around 8psi. No engine codes either.

Can you monitor rp desired?

Unfortunately not at the moment, only have a mini max for gauges.

Anyone willing to try to roll into the throttle around 60 mph and watch what their rail pressure does with the converter locked?

Should go to 24k that's what most trucks do
