does anyone uses the turbonetics mbc?? im wondering how i hook it up cuz last time i hooked it up it spiked up to 1.5 bars and the wastegate is about .7 bar... on the mbc theres 4 port and on one of the port theres a arrow pointing inwards. what goes where? last time i just ran it like this, intake manifold vacuum to mbc and mbc to wastegate side port

and it was set the lowest last time..... untighten and when its untighten i try to blow thru it and no air goes thru it. did i do it right?

plug the top and bottom holes, and connect a vaccuum source to one of the sides, the back side. Then connect the other side of the controller to the top port on the wastegate. I had mine and it only spiked a little, never double the wastegate spring.
