i have check all Vac lines ... my vac is 18 on idle where it is suppose to be ... so i am really lost where that is concerned
It could be so many things that can cause your car not boosting.
- Fuel cut
- ECU is in low boost mode and prevent TVSV to open due to errors from knock sensor, intercooler level sensor, etc..)
- Clogged cat
- Stuck open wastegate
- Bad turbo

how much boost have you been running?
what are you using the safc for?

Should be around -22 when your car's warmed up.

do a boost leak test to see where the leak is if there is one...gotta be a pretty big leak though if you have "no" boost. Other than that, maybe the turbo's gone.
