@bootht99 no its because i had the throttle body drilled out but i didnt debur any of the edges making it a whistle similar to when you have a bottle and you blow on it to make that deep horn noise however with the throttle body since the holes are much smaller it would do the noise at a much higher frequency (whistle). I could recreate this whistling noise while i drive and i could recreate it continuously, in other words i could speed up with the engine whistling.
If it wasnt for the lack of a blow off, it sounded like a real turbo in boost. The reason for the short whistle in this video is that it required the butterfly plate to be at a certain angle for it to whistle and back then when i shot that video i did not know that so i would turn the butterfly when i hit that angle it would whistle and then stop since i would pass it.
Nope, not a leak. No place to leak from since i didnt have to take any hoses off when i took the tb off. When i bored it out, i didn't round off the edges which is what (i think) causes the whistle. :)
i think its just from so much more air rushing in

thats normal. my xj does the same thing when you take off the intake hose and rev it.

Youve got a leak somewhere. Make sure the TB is seated properly and the check your vacuum lines.
