Anyone got or used one of these powertek MBC?
 

As above really, was going to go for a DAWES but wondered if this would be just as good. Personaly I think they all look the same (some brass plumbers fittings and a bit of rubber hose).

I am suffering from leaking boost so thought one of these may help control things better.
