    could be turbo noise, could be a leak, hard to say...
    got a monitoring device?

    Could the clamps or filter be rubbing on something? Just throwing it out there.

    Please use sentences and spell check next time. Very difficult to read your post.

    if its a really high pitched whistle, its an air leak - assuming you know what a turbo sounds like normally!

    Stft (short term fuel trim) and AFR
    If boost leak, AFR will be lower, and stft really negative
    If pre-turbo leak, AFR will be high and STFT a high positive number (car adding fuel to compensate for lean AFR)

    From stock, to GT3071, to substantially less modded, many lessons learned!

    Am guessing cause it's a metal TIP you're just hearing a lot more noise than you're used to

    I'll try and get a video of mine to compare if you like... I just installed a CS SRI a couple of weeks ago. I'll admit the noise is very different and would take some getting used to... especially for someone like me as my MPS is my first turbo car.
    Try doing some logging using the AP and go over the data I guess.
