i have a turbonetics MBC and i wanna verify that this is how u hook it up

1st vacuum to hks wastegate side port
2nd vacuum tee'd off to bov, and mbc, and mbc go top port of boost controller

is that the right way to do it?

what the difference from doing it like this

1st vacuum to mbc and mbc to wastegate side port

 

Manual boost controllers only get attached to the side port on the wastegate, so the second way you listed is correct, from intake manifold to MBC and then to the side port on the wastegate. The top port is for use with an electronic boost controller.

 

you basically just hook up the mbc in between the boost source and side port on the wastgate
