I have an aem CAI.... its not the same sound as when you FLOOR it, just wanted to know if thats what im faintly hearing when I accelerate lightly up to about 3500-4k rpms and it seems to sound louder before the car is warmed up completely, some people said they hear this so its probably normal. Sportmode, yea its kinda like a whistling sound but more so like a "rrreee" sound, hard to explain w/o hearing it, is yurs louder before the car is warmed up also?
