I have installed a Tial BOV on the up pipe before the throttle body and wanted to know which vacuum line to "tee" into. I read somewhere that the line you tee into must be at least 1/4" or straight to the intake. I am currently tee'd into a 7/32" vacuum line that goes from the vacuum block to the canister near the air filter. The hose I'm using from the bov is 1/4". With this current install, the turbo still "sneezes" when I let off the throttle, no whoosh sound. So I'm not sure if i am tee'd in the right line. The setup I have is a PT67 running a minimum 21 lbs on alky. I also have the vacuum brake setup. If you have any pictures of your working setup (close up of the tee'd vac line), that would help me out a lot. Thanks.
