Boost Leak

[450whpGSX]

when in any gear i give it a little gas and the car starts to pick up but at WOT there's a sound like a hissing sound or compressed air soming out. could this be a boost leak or a blown turbo?

Is there anything on your car that doesn't leak? Sounds like boost leak, at least eliminate it so you can move on to something else.

edit: Or it could just be the turbo spooling.

Could be a boost leak, but if you have replaced your stock airbox the sound of the turbo spooling will make a somewhat similar sound. Only one way to know for sure...leak test it!
