I was wondering where every one is getting there vacum source from. gonna be starting the instalation of my turbo pretty soon so im trying to figure out where to get the vacum for my guage, bov, wastegate ect. my truck is a 06silverado with the 5.3. thanks in advance for any help.

 

Splice into the line going off the back of the intake to the brake booster. I reccomend some kind of manifold to keep it all clean. I know a lot of people make them or there are some on McMaster (Type in manifold in the search on their website), my buddy is running an anodized black one on his setup.

I have yet to look at his, but it has to look better than a bunch of tee fittings....
