How does a boost controller work?

I have a turbo xs boost controller the manual kind,exactly how do they work?

they controle the amount of air pressure going into your tb.

I'm SO GLAD you asked that question! scottsee that's an extremely vague answer, you just said "a manual boost controller controls boost to the engine"

Good luck reading!

im good at being vague =)

To accurately answer the Q... A boost controller controls the amount of pressure that there is from the turbo all the way up to the intake manifold... Your/all turbos have a wastegate(internal,external) that is opened and closed depending on the amount of the pressure that is built up...a boost contr. changes when/how much the wastegate is opened/closed. If you are going to put one in, anyone with knowledge of this will tell you to install a numbered boost guage so you don't end up OVER boosting and getting little demons in your engine. Hope this helps.
