Trickflow Upper Plenum users..

I have been meaning to ask this for a long time, and have heard different responses..

For those with the trickflow upper plenum..do you have a distinct whistling noise coming from it when you hit the gas? I'm not talking about the noise from a CAI, they have two seperate sounds..almost like a mid-high range pitch constant sound when you accelerate. Just making sure it's normal, I've heard it is.

that noise is common, not just with trickflow, but with many plenums.. nothing to worry about G

I've got the TF plenum combined with a Ford 70mm and no whistle here. Nice SOTP pickup.
