So when the boost controller is completely closed...it is boosting 15 psi? That doesn't seem right. Some boost controllers are very sensitive to changes. Try opening the boost controller just tad bit.

manual boost controller
I got a ball and spring manual boost controller from ebay. i put it in.. and it seems the minimal boost i can get is 15 psi. I want to run 11 because I have a t25. Any comments on why it's doing this?.. is there any way i can alter the boost controller?

I figured out what the prob was. my friend threw away the instructions.. come to find out, i had to switch the two lines around. Stoopid mistake!
If you are running low boost you can shorten the spring, or get a different spring as well. Then the adjustment screw will not stick out as far from the MBC and get tangled in things.
I bought one on ebaY as well and I was having a similar problem. I just cut the spring so it was a little shorter and it worked perfectly after that. You can also get a softer spring and it will do the same thing.
