low boost, hissing sound

A pretty much stock 94 5spd with the stock plate full forward, timing 16* and a boost elbow installed.

Two questions:
My boost is about 17-18psi max, I still get pretty decent gas mileage 19mpg on the freeway. Are these turbo psi number low?

When I run a/c and shut the engine off, I am hearing a loud hissing noise coming from the front radiator area. Is it normal? Or do I have a leak somewhere in the condenser or turbo intercooler tubing? The a/c still works great.

Thanks!
Denis
