it's just air flow man. every car makes a "wierd" noise at some point or another with an aftermarket intake that flows really well. don't worry about it.
I was a retard, and now I'm permanently banned.
 
lol that sound is normal...just sucking in air
 
 
Actually AEM is somewhat known for that "chooom" sound.

anyone get the almost bov sound when shifting at redline? ...that may be due to the throttle body spacer i put on before i knew it did nothing though
