In my opinion, if you fit an intercooler whilst still stage 1 it is perfectly safe to up the boost (don't go past 20psi), and you'll probably get a bit more power as you're running it a bit leaner.
You ideally need to up the boost at least a little bit because the pressure loss across the intercooler will give you a lower effective pressure at the manifold, although I think this is counteracted by the denser charge coming from the intercooler.
