I have a 2011 STI and I have a GFB BOV installed on it, recently I've noticed that at low rpms 3.5k and under when I shift I get some "turbo gobbling" which seems like it can be fixed by loosening the preload on my bov, but if I do that than when the engine drops to idle it hunts for the right rpm before settling, which I was told is bad as the car could possibly stall. So what do I do? just try and find a sweet spot where I get as little turbo chatter as possible while also as little hunting too?
Fyi I'm running the cobb power plus tune/package as well
Also the video doesn't do a very good job at displaying the chatter
