IAC Whistles when bad?

"THESE IAC MOTORS GO BAD AND THE CAR DEVELOPS A WHISTLE. IF YOURS IS, TRY THIS"

This is a clip from a Ej22T IAC for sale on ebay, Is this true? i noticed that my SS has a Whistle now after swapping the motor out, however the new motor has more power, yet when i start her up, the idol goes to 2.5K and stays for a second, then slowly goes down to around .750k (my other engine would go down faster to .750k). The only thing i notice different from my other engine is the gas seems to take a little longer to calm down then my other engine when you hit the gas when ideling...and she has a whistle, i just figure that motors differ, and that the turbo is what i can hear when ideling...any other input on this??

Is the hose cracked?

No, they don't whistle when they're bad. I had some whistling when I swapped gaskets on my n/a motor.

i got A WHISTLE while i go around 2k rpm so this could be intake gasket?

[Legacy777]

Without a little more diagnostic work, it'd be hard to say for sure whether it's the intake gasket for certain.
