Its just odd that the car has absolutely no symptoms. Even if it is my FPDM is there any issue from this?

do you have any type of way to monitor your fuel trims? like a handheld tuner or even one of those little code readers? that would be a good way to see if it's really that high of psi, because at twice what it should be it'll deff be running rich.

Nope. I did have a scanner tool but a friend borrowed and never returned it...

Don't sweat it, if the car runs fine then its fine. It can be tuned out a bit, but there will always be a spike on returnless cars. Read this thread for more info.

Idk i was told if the pressure is too high it can get in vaccum lines and into the plenum but idk?

You would think if the 100 psi was bad i would notice on how it runs. Runs perfect with no issues. I would not even know if it were not for the gauge. I still think i should work on fixing it. I think im going to buy a mechianical gauge soon. Its not really important right now. I got bigger stuff to deal with like my SRA swap and my IRS sitting on the ground lol.

Only if you burst the FRPS. That can happen with high transient spikes.

Then don't worry about it

Did you try your buddy's FMDM?

I will say atleast the fuel isnt cutting out.

no i havent.. I wanna test the mechanical fuel pressure. if its really 80 psi etc then i will fix whatever it takes. If it shows normal then ill just forget about it till i have some extra cash to investigate.

If you don't want any spike then your fix is going to be a return fuel system. You can tune it down, but you will always see a blip in the datalogs on the returnless fuel system. Throwing parts at it will do nothing. You can remove the pprv and that may help a little (and is free!)

It shouldnt spike on every single rev. Regardless of my fuel system 100 psi every time i hit the gas is not normal.

Its far more normal than you seem to think, but 100psi is pretty high. It could also be that your gauge is out of calibration, or if its electric it can be over reacting. IMO aftermarket electronic FP gauges are all crap. The frps in a datalog is FAR more accurate, but I know you are not using that because the sensor pegs at 90psi.
