Yes the air door is spring loaded and you can put more or less tension on the spring. Most are saying to put more tension on the spring and not let it open. I may need much more tension..
I'm pretty sure the secondary door is spring loaded. Here's a full-out picture you can see the spring wrapped around the rod...

the spring adjust how fast the door comes open. But, there may be a way you can adjust how FAR it comes open as well. That's critical as well. When I was running TQ's years back, they had a tab that you could bend (it was slotted to bend) that controlled how far the door opened, and the spring controlled how quickly it opened.
