Three point manual boost controller

[Ollieh17]

Firstly, i know manual boost controllers aren't the best but it is tempoary until a get a ebc. The 0.3bar wastegate spring isnt cutting it. And i want a bit more boost for the drive down to japfest. Also i know this has been covered before, and im aware how to fit a two point controller.

My friend gave me a controller that looks like this

I need some instructions on where to plug the vac lines to and from. Cheers

It's most likely the air flows through the two sides and then once u open the screen it bleeds some air out the bottom. Blow into one of the side ports and screw the valve and see where the air starts to come out

Yep the bottom port bleeds to atmosphere.

Bleed valves aren't the most stable thing to be using, if you want to use a mbc then a relief valve is a much better choice

Cheers boys, i had a relief valve but lent it to a mate and hes away for a while :(seems to be okay so far
