You need to do a boost leak test...

The hissing sound could be a leak, it might as well be the hta71 through the specific filter you are using. If you have increased boost threshold and not making the right boost level at the right rpm point, then you have a leak somewhere. Remove blow off valve and block the pipe. Check every hose connection, every vacuum hose. Put the car into 2nd and floor it, see if it behaves as it should. If not, remove the hose from the wastegate nipple, again into 2nd and floor it, see if it makes boost the right way.
His load values will not be negatively affected if he has a major leak, as the air going into the engine and measured by the map sensor is much less than it should when his boost threshold and max boost was the proper one, unless of course he is still on MAF.
