all the vacuum lines are plugged up or plugged correctly in. what should the vacuum be at? 20psi? it might be the gauge.

 

if i remember correctly its 18-20 mine is at 17 maybe gauge is alittle off...

 

im not sure what my exact vacuum reading is but why is it off? leak in 1 hose?

 

mines usually anywhere from 18-21

 

mine is always at 21.

 

i've seen a stock wrx with a vacuum of 18 or 19.

 

what kind of cars are u guys running to be boosting 18-20 psi?
