Must be something to do with the MBC spring stiffness.. adjustment bolt falls off if I loosen it too much to bring the boost down. I have to disassemble the whole thing to see if there is a problem. Currently using GM BCS but I like the idea of hybrid boost control a lot. My boost lines are 4mm silicone hoses and the lenght is as short as possible.
