Default Single vs. Dual Solenoid Questions

What is the difference between single and dual solenoid boost controllers? I am only looking to get maybe 5psig make gain out of stock my04 turbo. I am thinking the Greddy Profec B Spec II. It is not too highly priced and still has a decent display module. Any comments on that particular controller and also, what is the deal with the # of solenoids? Thanks.
