Would having a hole in my rear brake drum line be throwing my psi off?

Idk how the brake booster works..... i was thinking maybe with the brake fluid out it was maybe causing a brake booster vacuum leak and throwing it off....

Noooooooooooooooooooooooooooooooooooooooooo. Brake booster just uses engine vacuum to reduce effort at the brake pedal and increase stopping power.

Boost is tied into the vacuum pull of a car. Thats why i thought it might.

there is a small grey valve in line of that from the manifold to the booster that is a one way check valve will only use vacume not let boost in so no it has nothing to do with a boost leak! most common causes are bov leak or couplings not tight enough even a compressor housing leak or exhaust leak up stream of turbo.

Ok. Thanks for your help instead of laughing. On high boost which is twenty lbs, and low boost which is 15lbs it only goes to 13 lbs. On wastegate pressure it goes the full ten lbs that it should. Would it be a leak, or maybe a tune issue?

check your diaphram in your waste gate. seems waste gate related to me.
