Had a boost gauge installed and it was tapped in the evap solenoid? On the left side front of intake manifold next to throttle body....and got a evap cel....he cleared the cel but still only seein 6-8 psi....disconnected battery and cleared ecu...no cel but still same boost....is that a wrong location for the vacuum line?....i disconnected boost line and ran it oem way and still low boost

 

It's supposed to be tapped into the BPV vacuum line

 

ok that makes sense but when i disconnected boost vacuum line and ran the hose how it was before im still seein low boost like its in limp mode but no CEL?

 

Yup tap into BPV vacuum line by using T-tap adapter. You won't see boost go up if car is idling and when you try to rev but will see it once your moving. at least that's how mine works.
