My 2 pence, having done the exact same build, would be to run at 24 psi and map it up to suit. Don't go for a higher power figure than you can run on the turbo, otherwise the upgrade is fairly pointless. You'll get 170BHP (or so) on 24psi, and it'll hang on a lot better than if you push the figures up.
By all means, go for 200BHP. But it's a different set of specifications than the build you've started. You'd need a bigger turbo (and probably a better exhaust manifold), more fuelling mods (££££), head studs, modification to the head to stop it shitting the valvetrain, forged internals and crank modifications if we're going above about 230BHP. Etc...
And feel free to prove me wrong, I just think you'll run into issues very quickly if you run too much power/boost/EMP/EGT etc...
