tolerances are in the hanynes manual i believe. there is a kinda wire that you can put on a place you want to know the tolerance. It will become flat and the width stands for a tolerance. I don't know the name of em at the moment.
If you disassembled your engine you probably had something wrong. If something was wrong with the engine i would suggest putting a new on. There is nothing worse then building a engine and destroying it because you reused your pump. How was the oil pressure before the engine got disassembled?
Get yourself one of these if you don't have

hi. he broke the camshaft, metal in the oil, it broke turbo, pressure remained plugged,
but the pump is new and has no gaps, disassemble and everything seems ok, dense sucker,

Measure it, put it on, run it check oil pressure if any doubt about the oil pressure bin it and put a new one on. Ofcourse don't let it run too long if you doubt the pressure. There are a lot of topics about oil pressure at idle when hot.
Don't trust a electrical sensor, go for the mechanical onces

Why do you need more pressure? Are you low on pressure now then? isn't there something else wrong?
What are your pressures at different rpm's?

You shouldn't need to add "false" oil pressure by adding a different spring. Running it as standard should be plenty and if it's not correct then I would say there is a problem. Adding a different spring may just mask the problem for a short period.

If your driving and the oil light comes on at least you still have 20psi at least at that point and get a second or so longer to turn the engine off.
Where as if it was a standard switch at that point it would be very low pressure and more than likely makes more damage than what ever has already happened.
While driving it comes down to many factors like, pump, oil lines and remote setups, filter, etc etc..

as someone said it could be something else wrong but for the cheap cost of a spring it's worth doing anyway.

IMO That's a poor idea, a CVH at optimum running temperature (say after a half hour drive) will idle around 14psi meaning the oil light will be on all the time at idle... so if you do actually have low oil pressure you would never know.
