boost gauge install

i got the autometer boost/vac gauge hooked up and i think im in the wrong line because theres no vacum pressure ....where id the best place to hook up the boost line.. I heard you can hook it up to the greddy type s BOV... Is that ture???

hook up to the fuel pressure solenoid, that's the correct way to get vac/boost. the trick is to do a good job and hook it up tite so you won't lose the fuel pressure.

and that will mearsure the boost and vac from the the turbo???

yes, just make sure you do it right. do a search in google for "boost gauge install, dsm"
