01 GT hesitation

Help!!! My 4.6 hesitates with sucking-air sound when I tromp or blip the throttle.
TWO Ford mechanics have run diagnostics - no codes - all data within parameters.
Embarassing at autocross events. CAI had no effect. Possible cracked plenum or throttle body????
Dont want to waste $300!
Thanks for anyone's knowlegable input
