Does anybody know the standard boost figures for a 1996 STi 2.My new gauge is reading 15 psi max dropping and holding to about 12 psi.
I want to get it up to 18 ish

Cheers

That sounds about right, to get it past that you should look at a boost controller/fuel riser, but holding 18psi (peak at about 20psi) would be close to the duty limit of your injectors.
