Default Help to locate boost hissing noise

Anyone good at identyfying loud boost leak noises and locating them?
Prefer not to hassle Tim Cooper at RENN TECH too much as he must be fed up of seeing my heap this year. Basically get to 0.5 bar and the hissing starts, By 1 bar its very loud and I back off to avoid possibly damaging something, so not very nice to drive at the moment and unable to enjoy the new exhaust note,
