Throw the stock bov on. You’re car will thank you, and it will be quicker into boost/less rich in-between gears. Yea, you lose the sound of VTA, but the gains are a better running car, and more efficiency. Do what I did, trade the aftermarket for a stock bov+cash ! ---

Do what I did, trade the aftermarket for a stock bov+cash ! +1 It is because the car reads the amount of air coming into the motor before the blow off valve, so when the valve opens the car goes rich (since there is now less air and the same amount of fuel). ---

no , the b.o.v is not causing this code . most likely its a broke vacuum line or bad evap purge solenoid . it is part of the fuel vapor managment on the car not the b.o.v ---
