Can't see that causing boost creep that's just crank pressure. It's odd that he has the one side just open like that, most remove the pcv and put that hose in its place.

Port the hotside / dump port. Make sure you don't have any restrictions in the exhaust where the dump port rejoins the main exhaust or switch to an open dump.

Creep usually has nothing to do with the boost controller (though i have seen the ball stick in a few cheap mbc's), but rather the ability of exhaust gas to bypass the turbine at higher flow rates.

Stiffer spring will only make it worse.
