Help With N55 and MHD

On my E82 N55 I am only making about half of boost target at WOT according to my MHD logs. The target is 10.9 and it is making 4.9 and the highest boost I have seen is about 6PSI The car has VRSF intercooler and charge pipes. It would seem to me that if I had a boost leak the WGDC would be near 100% but I am seeing about 45%. Am I over simplifying it or can you use WGDC as an indication of boost leak?
