If you are staying stock turbo, forget the BOV. I ignored what everyone posted about how useless they are, bought one then got rid of it and went back to stock bov. It through my AF learning off when I ran a datalog
Correct me if I am wrong guys.
Maf expects a certain amount of air that should be there for the turbo.
when the BOV releases that extra air for just some noise.
The maf wont have that extra air to read and so it would kind of being in limp mode but worse.
Pretty much to have a BOV you need to have some good modding done as well as a ProTune not just and OTS map
Okay OP you are running a MAF system which means the air that has entered the air intake system has been measured by the sensor. The ECU thinks there is X amount of air in the system and adds fuel based on boost pressure, temp, etc. You vent that air into the atmosphere then the ECU still thinks there is X amount of air when in reality there is less than X,
