Hey guys i have a 2014 WRX.
Mods- Invidia DP, Cobb SF, Turboxs BOV, Cobb Stage 2+
Im experiencing what i believe is a boost leak but I'm not sure. Im still hitting peak boost every time, but i hear this loud high pitch sound under hard acceleration. The best way to describe the sound is a tea pot on the stove. It doesn't make this noise every time, and usually only in 2-4th. It only last for a second or two. Ive already checked my DP, BOV, Throttle body hose and every other line i can and no luck. Ive been looking on the forums for a similar post/sound and can't find anything. Any help would be great, thanks!
