We're installing a manual boost controller onto a gsr with a drag kit.We're also installing a golden eagle vacuum box. Do we need to have a direct line from the vac. manifold to the side port on the wastegate and then run a vac. line from the top port on the wastgate to the boostcontroller and then to the vac. mani. Or should we leave the side port open and just have a line from the top port to BC to vac. mani? THanks yo

 

you need a vac line from the side port of the wg to a vac source. the manual boost controller will tee into that line. the top port of the wastegate should be left open, no lines will run there with your setup.

what boost controller are you running, im sure you could find some better insructions on the manufacturer's website. or with a quick search on here.
