Noisy injectors?

That's what that noise is! I installed an open element and since then I started hearing that noise but I didn't think about it. I kinda didn't like it at first but now I think its pretty cool.

after a little playing around with it i noticed that it is REALLY loud when its cold but when it warms up it goes to the sound i like. the sound you are describing

Some of the hiss you are hearing is probably the idle air control valve (IAC). As the engine warms up the valve closes a lot but not completely. The injectors make more of a ticking sound, I've never herd mine hiss before.
