Okay so i just installed my boost gauge and I have a few questins. My first being when my car is at idle i have a vacuum around 15psi is that normal?, my next question is where should my psi be at at WOT, mine sticks at around 10-16psi, and my last question is when i drive around normal i am at about 17-20 vacuum psi thast keeping it under 3000rpm. oh and I almost forgot i can hear the air coming from my gauge a little i know this is probly not supposed to happenI was wondering if any one else has had that problem and if so how did you fix it.Feedback is greatly appreciated.

Thank you.
