2wd Sapph boost problem

Slight problem with the boost at the moment it won't hold over 10psi usually it runs about 20-24psi, I just get what sounds like a rushing of air any idea whats going on

It does sound as though its coming from the side that the dump valve is on so would that make sense then for the loss in boost ??
