It's a bit trial and error mate, have you got an oil pressure gauge? Best thing to do is to shim it 1mm, check your oil pressure gauge and see if its where you would like it to be. If not go for 1.5mm.

Why are you shimming it?

new build i hear 5es suffer from oil pressure problems

I would see how it goes, too much oil pressure can be just as bad as too little oil pressure. You got a gauge to keep an eye on things?

I would wait and see how your oil pressure is before doing anything..

seems most are running the washer in the 5es thats running big power ,

If i were you i would wait and see what your pressure is going to do 1st before shimming anything. But its up to you
If you search on here it has been covered before.

ive been reading on a few sites they seem to opt,, for putting the washer in as 5es suck with oil pressure when turboed running big power

It's not so much the power, it's the rev limit. Higher than stock 5e rev limit and it doesn't flow enough at the higher rpm's. If it was me I would try it without a shim first, get the engine run in as you won't be going near the rev limit to run the engine in. Then see how it goes after that.
What rev limit are you looking at setting? And what turbo and boost you running?
