Another confused person on MBC setup?

[Drftn93SR]

:squintd:So I am wanting to get a little more power out of my setup, so i thought maybe i could raise my boost. Correct me if I'm wrong... I have a vacuum line from my throttle body to my BOV, and i have a vacuum line going from the wastegate to the bleeder side of the MBC, and a vacuum line going from the turbo nipple to the ball and spring side of the MBC, it allows me to pull extra boost, but when i go into boost, i just keep building it, it gets to 15lbs and let off before i overspool.... what is wrong with my setup...?

What car is this?

Assuming SR, your BOV sounds like it's OK, if you're using the fat nipple on the TB straight to the BOV.

The boost controller may or may not be backward, and/or not set correctly.

Can you post the model of the boost controller? Or better yet, find the instructions online for the model if you can.

I don't know if you have the lines hooked up wrong, or if the adjustment is just way off.

Also, how are you reading boost pressure? Is your gauge good? Where did you hook the gauge to?
