so heres the deal, i have a boost leak. not sure whether it is in my hoses or my N75 valve. my BAD question is, are there two different things, vacuum and boost lines, or just one such thing. if there are two, (im really sorry for asking. this is a very easy question i know...) what should i replace first to find my leak? my k04 on GIAC is only boosting 15psi, and i used to be 18-19psi. my vacuum at idle is at 24mm/hg

Hmmm...I would pressure test it and locate where the leak is coming from...and oh yeah there are only vac lines no "boost" lines. Why not just replace all of your lines? Vac line is cheap haha.
