10 psi is plenty to get a great finish. I only run 6 psi to the cup, which will be less than yours, and I get plenty of fluid flow. Of course, you have to open up the needle enough to get sufficient flow. Maybe that's where you are going wrong. Don't worry so much about perfect atomization. Worry about what set of conditions gives you a perfect finish. If it's dry then you don't have enough flow or your gun is too far away from the surface.
If your gun can generate 10 psi it has more than enough capability to spray Emerald Urethane Trim paint very well.
