I forgot to let you guys know, i taped into vaccuum line from FPR to manifold, is that ok>?

 

yes that is how you install a boost guage, you can tap into the dv line but it wont give you a vac reading if you do that. I would check the L hose located behind the intake manifold as it is very common leak spot and prone to cracking.

 

Cool, Thanks guys , i will check the L hose and also the rest.
