Hey there, I’ve recently brought a 2006 WRX and am about to start modifying it. one of the things I wanna get done first is a boost gauge (because why not). I was just wondering where I should get my vacuum source from? I’ve done a bit of research and come up with everyone just going off the BPV/BOV Hose but I’m a little sceptical? should I just go off there or is there a better location? if you can help that’ll be great, and if there’s any chance of pictures that would be amazing!!!! Thanks in advance for the help!!
