everytime on light throttle.. high pitch whistling noise starts.. not even boosting
actually the sounds is higher on cruising on vacuum pressure. i have no boost problem what so ever.. runs normal.. the sounds actually starts out with a little fluttering noise then like a diesel turbo noise.. anyone can help me diagnose this? i dont know where to start.. i hope my turbo is not blown

If you say it sounds like a fluttering sound, it might just be compressor surge from your turbo.

What you're describing kind of sounds like this... VF34 Compressor Surge - YouTube

Is that correct?

I also have a slight whistle while in vacuum pressure, I think it is normal turbo noise that you get when you have an aftermarket downpipe. I could be wrong though.
