Every truck I've ever owned, Ford and others, did the same thing.
I prefer it this way as opposed to the alternative.

Same here. It is normal. Even seen them go as low as 15 PSI when under strain. If it fluctuates intermittently then you may have a problem. Most of the time, though, it is the sending unit when that happens.

I just put a set of walmart mechanical gauges into mine and it has about 60 when idleing when i first start it and once the oil gets warmed up it will drop to about 25- 30 psi when i accelerate it goes back up to about 50 - 60 so i am assumeing thats normal. When i had the factory gauges hooked up with the new sending unit it would go off the chart and then run in the middle of normal so i think ur fine.
