Ported and Polished Throttle Body

Sure if there is a large diameter cold air intake with an equally large air filter.

Will a ported and polished throttle body make a whistling sound when the gas is applied?
 
did you grind off any "bumps" inside that were upstream (right in front of) of an opening (say for IAC, PCV, vacuum, etc.). The bumps that are in there are to eliminate whistling.
That's my guess.
