I installed an AFE Stage 2 intake (the sealed version) on my 5.7 Tundra and have a question. I am hearing a faint whistling sound under partial throttle and was wondering if you guys hear the same sound? It is not present at idle nor under heavy throttle. All connections are good and tight and the hose fitting that was partially/fully blocked in some early versions is fine too. It's not a big deal as the radio pretty much drowns it out, but I would feel better knowing that I didn't do something wrong while installing it. Thanks in advance.
