Hello everyone!
Lately I have been hearing a weird sound coming from the intake/diverter valve everytime I shift. Usually I hear a single pssst everytime I go though gears but lately I have been hearing a "horse breathing" sound which is weird. I have no check engine light on, my car has 59000 miles and I've had a JB+ stock dial for almost 10000 miles, I also have a helix intercooler and an open filter for intake(apexi filter). I uploaded a video of the sound

Thank you so much for your help, I have a long commute everyday and I don't have to be stranded because of it.

 

I heard a similar sound but did get the dreaded yellow 1/2 power engine light. My 2012 All4S CM has approx. 32k. I am only getting max 6psi of boost also. At the dealer ( with the JB+ removed) it was diagnosed as a defective BOV. They had to order the factory BOV which will be installed this week.

 

Thanks for your help!

 

your video sounds perfectly normal to me, the huffing sound along with the pshh is normal.

 

Sounds like downshifting in the original Fast And Furious movies! Has to be a change in the BOV, possibly the spring inside or another internal diaphram part. It doesn't sound bad, just different that the minis I have heard recently.
