I just picked this up from someone online. When i received it, I noticed it was missing the two rubber o-ring on the controller. Without it, it would exposed 2 little vent holes. So I found a rubber o-ring that was slightly bigger and used a zip tie to make it fit better.

I spent 30mins trying to get this controller to work. I took it apart and notice that the stem to increase boost didnt seem long enough to control boost. Is my mbc missing something? Or should i remove that zip tie and lave the vent hole open?
Can someone provide pictures of what that stem should look like. Thanks
