whats your boost read when idling mines -20

-20 is correct, anywhere from -19 to -20 is good.

and when you rev it how much psi should you be getting out of the car. all i have is an air intake and a new cat but its stock still

you shouldnt get anything when you rev it. the motor needs loan to produce boost.
