Well since im having to wait around a week or so to get a new bracket made up for my actuator i've bought a shitty MBC to try and up my boost a bit. I couldn't get anything over 0.3bar before (just on the actuator) and since ive installed this MBC i can get 0.67bar. Just wanted to make sure i've installed it correctly. I've correctly connected up the 2 boost pipes to the controller but then the controller itself has a third pipe coming from it. Am i right in saying this is to ventilate? Heres a picture anyway:
