It was the intake adjustor. Replaced it. Unplug the electronic connected. Remove the torx bolt....replace with new intake adjustor and rebolt and replug. No more whistle.

Interestingly enough, my low end torque is much more powerful. Hmmm...I guess the intake adjustor makes a difference. It is part of the variable intake system which allows more low end torque with choosing the longer intake pathway @ the lower RPM and more HP @ the higher RPM with shorter pathway (better breathing!) The part cost $150!

See part#7....
