Wierd chirp

[twack]

About 2 weeks ago i installed a 2g throttle body elbow, now ever since it makes this wierd high pitch chirp when i let off the gas, this happens at about 50% throttle or more. its not bov cause it happens right after and some times its not even in boost and it chirps when i take my foot off quick, any help???

If its a metallic sounding chirp then I'd say its normal, my car did that once I installed hard IC piping.
