Default MBC issues

When I had my car rebuilt the builder said it was running a manual boost controller which I didn't know about because I just had bought the car used.

I found some torn vacuum lines and split oil breather lines. I replaced them and now the car is staying at just below .05 bar boost.

Im running cobb stage 1 and it sits right at .1 bar but dropped down and stays right at .04-.05 bar after I replaces those hoses. Doesn't make sense?

I have no clue where the mbc is an if that's what causing. Any help would be really appreciated. Thanks!
