Please get in detail. When does the noise happen? What does it sound like? How do you know it's the turbo?

i know this sounds funny but it sounds kinda like a cricket churp. I know its the turbo because it happens after about 5 psi of boost. it onley makes the sound under load.I just put a top speed header and a titek downpipe on.
