so i have a 1.8t
k03 turbo with 25k
turbo inlet pipe
intake
n75 race valve
turbo back exhaust (3" cat delete pipe to 2.5" downpipe back)
Giac chip boostin 19-23 psi
stage one clutch

when i so open throttle "full throttle" there is a sort of ticking sound coming from what i believe is my n75 valve but im not 100% sure. i really hope its not coming from my turbo "shaft play" maybe i dont know.
its only when im boosting about 15psi when this occurs. please let me know what i should do, friends have told me to get a fmic or bov or oil catch can.
i need ideas i dont want to blow my turbo or anything
