So I figured this would be a good thread to have for those with the stock BPV. I can add to this post if others have more ideas.

Since we have a diaphragm style BPV stock it is prone to tears and I have seen some reported as early as 1-2k miles on the car. I honestly think that this is where kia/hyundai dropped the ball on us and gave us something that is crappy.

So here are some signs your BPV may be going out or the solenoid

• Fluttering under WOT
• Consistantly hearing the BPV under any load
• Code p2261
• Boost pressure not as high
• No boost under any condition
• Boost fluctuating under power

These are basic symptoms of what can be a sign of your BPV having a tear or the solenoid not working properly. To confirm your BPV has a tear or not is either take it to the dealer or take it off yourself and check the diaphragm for any cracks or tears. If so you can replace the stock BPV with a TurboXS SML Hybrid BOV

My question is when 6th finishes his FMIC would the TurboXS work or would I need to get something else

I would only assume it would work for the 6th fmic as well. As most should be universal other wise companies would have a hard time selling BOV because you would have to make the same model in multiple different configurations. However I know the BOV that 6th is using is part of the fmic design and could be the only that could work with it. They would have to confirm it.

I also know a good portion on here is using the turbosx BOV right now as well

Just in aftermarket applications there are around 8 different BOV mounting configurations that I know of off the top of my head and I am sure there are more not including the OEM BPV from each manufacturer being different. The only thing similar between them all is function.

Thanks for posting this! It's been my only real issue but I want to wait on the BOV if I can til I get an FMIC
