Hey guys I'm not sure how to hook this baby up (vacuum lines).. but this is how I did it.... from the Turbo to a "T" fitting that goes to the wastegate and the BOV... but right before the BOV I use another "T" fitting that goes to the Controller and the TOP of the wastegate... but it's not reading proper boost.... HELP!!!!

 

if youre using a manual boost controller you only need to use the side port of the wg. where there used to be a single vac source line from manifold/turbo to the wg port before the controller, thats where the mbc installs. splice into it and connect both ends to the controller in/out. there are no tee's. the top port vents into the air
