I have ran vacuum source off of the brake booster line for close to a year now with no issues. There are a number of other spots that are post MAF sensor to reference vac from. If you remove the 'D4-S' engine cover there is a manifold to PCV connection. Underneath the intake manifold there is a nipple also, but that would involve deleting the EVAP purge solenoid....no one really does that unless they are using that harness for boost control.
