The TPI system is pretty noisy. Especially if your under the hood while your engine is running.

get some carb cleaner or something of that nature and spray it around all the gaskets on your intake, if you hear you engine jump in RPMs then you have an air leak....the leak willl suck in the air and the carb cleaner causing the RPM jump.

That noise is usually just the air rushng through the plenum. Because of its shape and size, it amplifies the noise which then bounces off the intake manifold, further amplifying the noise.
