Help! annoying sound on WOT ( video included )

Elie335i · 04-25-2011, 08:11 AM

Hello members;

recently I got a voice (whistling) coming from the engine bay area on WOT, the sound just appear on full throttle at 4k+ RPM, I logged, I'm off the target PSI with 2 psi, does it sound like a boost leak? please check the voice clip down.
Target= 14.5 psi pre-boost is 12 psi
running map 2

Thanks

It's a boost leak.
