I thought that they would basically stay closed until they were told to open.
Thank you for all your help guys.

They do stay closed until they're told to open. It's the pressure from the turbo that opens them. Without a boost controller, you're limited to less boost. A boost controller lowers the pressure on the line between the turbo and the controller actuator, allowing more boost than the wastegate would otherwise.
Here's the plumbing:
Here are the actual parts:
Without the boost controller bleeding off pressure in the line, the actuator sees all the boost the turbo's making and opens too soon.
