I have tried all the solutions i thought were the boost leak im hearing in the low end especially when driving in auto and the car is cold. First was bov, then turbo inlet hose/intercooler hose they have like 5 different names its a little irritating. Just did the intercooler to throttle body hose, although not specified on the part (mishimoto for g3 wrx) it did end up fitting which makes sense to me as but im no expert. is pressing slightly on the corner of the intercooler though. All these parts although they were leaking were not the sound i was hearing. its especially noticeable when the engine hits boost for the first time that drive and gets less prominent as it warms up further. Also when driving in auto you can hear it between gears if youre not higher in the rpm. im just looking for a point in the right direction, i have alot to learn about these cars still.
