no boost, loud air leak sound

just installed pinks the other day and so far have checked them for leaks and reseated twice just to be sure they were installed properly. When i go to hit boost around 3500 i hear a loud deep air sound on the passenger side and it feels like the car bogs down. I've tried all my maps in the utec that worked previous to the install. Can anyone help me out on this

You have a boost leak somewhere in your intake intake system after the turbo. When you say "pinks" what do you refer to?

injectors, so i have a leak somewhere where between where the turbo connects to the intake to the air filter. does the leak have to be big to get a deep loud air sound.

No. You have a leak between the turbo and the throttle body. It coule be anywhere in your IC piping.

2 out 3 problems solved. 1. paramaters for stage 4 not set. fixed. 2. turbo inlet hose but fully set on turbo fixed with 90 degree screwdriver and clamp good thing is was visible. 3. exhaust leak somewhere, alot vibration and noise on drvr/passenger seats. will fix after car gets out of paint shop next week sometime.

Installed greddy turbo timer 15 minutes long, good thing I've had practice on them, its one thing i didn't f up yet.
