Is this like a high pitched electronic kind of whistle or a whoosh kind of whistle? Sometimes under partial throttle accelleration you can hear the blow-off valve dumping pressure, sounds like a whooshing whistle. Under full throttle this should go away if your RPMs are up enough.

Another thing that can make a high pitched whistle that sounds electronic is a fuel pump.
