Boost leak problems

[Savagecbmk6]

I replaced my intake manifold and then check engine light came on and it said I had a bad MAF sensor I changed that but I'm still getting loss of power it doesn't feel like the turbo is really hitting it makes a whistle noise when at about 2500-3000 rpm coming from intake area and also sounds like extra air sound is coming from somewhere everything is tight I can't figure it out any help would be greatly appreciated thanks 12 VW GTI

re-check... theres a vacuum leak somewhere... check again with light.

check throttle body silicone pipe connector and the clamps. That tends to be a spot for leakage. Also PCV hoses tend to pop off every now and then because they are crap connectors. Just push them back on as tight as you can
