thank u for the write up! currently have a turbo x's hybrid 50/50 bov on my 12' wrx. only vents when i open it up and drives without a problem afr's read great too. only problem with it is backfiring which seems to be common with any VTA bov.
have any suggestions/opinions on any other bov's (50/50) that wont backfire?? or any full recirc BOV that will give any sound??
