Turbo help !?

Okay so i have 2011n55 sedan jb4 ,afe dp ,afe scoops. , bms intake ive had them all for about a month. After a week of having them i noticed a deep oooosh sound from 1500-4000 rpm and if i hold the throttle at 3000my turbo makes a bunch of chirping noises for like 3 sec then its stops same when i come to a stop i understand if back pressure hits the turbo it makes that churping sound but could it be my oem charge pipe leaking i also put map 2w/boost gauge and it only goes half way so i think there might be a boost leak so idk any of your guys expert advice would be appreciated 😃

Garage List
Chirping at fluttering sounds are completely normal with the BMS intake. It definitely makes more of them as you are light on the throttle right before the next shift. It's just the bypass valve opening and closing based on intake pipe pressure
