A whistle at partial throttle is pretty common. It has to do with the way the air flows through the CAI and the throttle body at this one particular RPM. Its usually at cruising speed when you are in and out of the throttle. Some are more noticable than others, and some dont do it at all (as it depends on the setup). Just giving me personal opinion on the matter.
