I've got a very audible air release/whooshing sort of noise when my car hits peak boost (23psi) from low revs, once I'm giving it some it doesn't overboost and runs around 18psi, I've been told this could be my wastgate not holding pressure, it still has a slight fluctuation in boost pressure aswell, could this be a result of my n75 needing replacing? Thanks
