Different size water pipes.

I put my regulator on which is set to 55psi and the shower flow was difference was quite noticeable as were all the other faucets, drink water tap etc.

Your regulator (the 2nd picture) is faulty or something else messed up, shouldn't notice the difference between 55 & 60 psi in your shower.

Please explain your theory on that seeing as how the water pump or city pressure will actually set the actual pressure.

Reminds me of an old plumber I met years ago. When questioned as to why he ran a 1/2" line to feed the 3rd floor of a building Stated the same idea. Problem is it is a false thought and there was a very limited flow of water going that distance. Could not refill the toilet and fill a water glass at same time. Cost him lots of $$ to replace as it should have been in first place. That's why buildings over a certain height have to add booster pumps to get water to upper floors.

I’m not talking about going vertical to another floor but if you decrease inside diameter of pipe, the pressure will increase in the smaller pipe but not when it leaves if it goes into bigger pipe. That’s based on aircraft Hydraulics when I was a mechanic during Vietnam era.

Yea, but it only lasts to the point of expansion. And the volume falls drastically.
Kind of like saying that if you put in smaller wire, and do not decrease the load, the voltage will increase. It may seem like it until the smoke clears but it ain't so.
