Your catch catch shouldnt be seeing boost, only vacuum.

Found out that its an air/oil seperator. Basically its leaking from there so ill just put a catch can on it somewhere next week. Even with only less than 10psi air running from my compressor through my turbo intake you can hear it leak air very loud.
Also, i doubt that my tuner tuned my car to run without the IACV. Because before i let it sit for 1.5 years my car would act normal once the iacv would open up more (70+ degrees celsius). Now after 1.5 years it has throttle dip in.
