House is 4700 sf
water line into the house is 3/4"
we have a culligan whole house filtering system.
The area is considered a high psi area so psi isn't the problem

Sounds like there is a crimp in the line somewhere. It's allowing the pressure to build, but can't deliver the volume.
We had that problem under a slab. Ended up having to saw a section out of the slab.

I would say 3/4 inch should be sufficient for your home, if not you can add bladder tanks to increase the pressure where you want it. 90# Yikes, mine is 65 and I worry, I put it in myself so I'm sure it will hold.
My guess is there might be some garbage left in the line by a plumber. You have to start at the front and work your way back, I've seen everything from solder to pieces of plastic come through a line.
This and, somewhere there's a crimp like suggested, things happen, I've seen things that would make you wonder in new construction. Maybe a pipe a little to long that was bent a little to much? who knows but, your going to pay for it.

Sounds like an engineering question. From the cuff it sounds like a very large house to only have a 3/4" main. Without knowing the layout I would say the main should be at least 1" an probably more like a 1 1/4" would be better.
I do except email.

I hope you have found this out while the pipes are showing? If so I would install at a min 1"
With that much pressure what type of pipe are you using? I think I would stick a regulator in to lower the PSI to save my pipes. Over time 90PSI will find soft spots.

is the valve by the meter all the way open? and if you have the main shut off out side has it been fully opened. when they test the water in a new home they only turn on the main shut off a little to fill the system. do you have kinks in any of the main lines?

Check that filtering system for a condition that might raise backpressure.
