Evo x whistling/whooshing noise

[eVolootion]

I was wondering if anyone else notices a slight whistling/whooshing noise audible while sitting inside their X and revving the engine around 2k rpms. It happens in neutral and all 5 gears for me. This sound doesn't occur everytime I drive the car. I do have an aem cai installed that was put on 2 years ago but just recently noticed the noise. I don't have any other mods under the hood except a boost controller that was set by RRE. Do you guys have any ideas what it could be??

This might be normal as I too have noticed this as well after installing my ets intake. I get it on light throttle. 2-3k rpm range. perhaps it's the stock recirc bov that we are hearing recirculating the boost around? Thinking this because we are on part throttle and car could also be slightly bogging from this. Maybe someone else can chime in?

check your intake couplers...
