So i have a symphony of various noises from my setup, when going on boost and when i let off the throttle
Kstech Megamaf 73mm intake
Forge recirc valve(yellow spring currently)
Perrin turbo inlet
Grimmspeed 3 port boost solenoid
Kinugawa 1 bar wastegate actuator
3" Turbo back exhaust
When in 3rd and building boost there is a noticeable flutter and lack of power while that noise is there, once it disappears it feels like the turbo is working properly, boost is the same with noise there or when it goes. Can happen in 3rd/4th/5th gears when going from maybe lower revs than you should be for that gear.
Second noise usually happens on partial throttle release, i think its compressor surge but maybe be wrong. On full throttle release after full boost the car is jerky, very on/off if that makes sense.
Lastly, maybe this is just normal when driving hard when changing gears or get fully off throttle quickly you get a swoosh/schwing noise.
See the recent trackday video and you should be able to hear all the noises im referring to. Can you guys help me out and let me know which are tune related and can be tuned out and which are hardware related ie. bov spring is too stiff/soft, possible torn hose etc, it will help make my quest to solve these issues a bit easier!
