Looking for stock fuel pump WOT psi

[Trqmnstr]

Im showing 40 PSI from the dig, 48-50 in second and 55+ through remaining gears.
Is this common for an OEM pump or a sign she is going out?
It jumps from 40 to damn near 50 upon upshift to second and then Crawls its way to 62 psi through the rest of the gears.
Roll on from 35 it drops to 53-55 and crawls back up.
116k miles, Blue spring, new filters, no leaks.

I'm not sure if it is common for an OEM pump but whenever I got my after market injectors I was told its not good for your injectors if its drops below 40psi

Ive read below 45 is bad for the injectors OEM or built but i cant find anything on time below 45 psi.
Is constant -45 psi the prob or just a sudden drop for a few seconds?

in highpo motors everything is crutial but this is just starting to crawl and i want a solid system before tuning.

So much of the drop is tune (PW) and nozzle dependant. What you are seeing may be normal depending on your tune. If you roll in rather than stomp it, the pressure drop is better managed by the pump. It is harder to build from a deficit. Don't worry about a short time at 40 psi or even somewhat lower. However, if you plan on running at WOT and low fuel pressure often, then you should plan on making a change to your system. If you are on a stock tune, it is time to figure out why you have low pressure and fix it.
