Do you have a throttle body spacer installed, I know that they make a whistle.

may be belt slipping when shifting at WOT, most of them do it, especially if you have a programmer that firms up the shifts

do you have an intake or a TB? Those are the most likely culprits, if you do.

if i were you i would first check out the air intake tube and just double check you don't have any debris in there that could be causing that whistle.

what you're hearing is the K&N. did the truck do it before you put the K&N in? I'll bet it didn't.

Those CAIs and K&N filters make a whislteing noise when at WOT, this is why some people don't like them, but this a also a reason why people want them(other than the fact that they give better air flow and create more power.

well i cant exactly rember if it did it before i got the K&N becuase i got the air filter about a month after i got the truck i wanna say it didnt thought becuase when i test drove it i dont think it did it, so my guess is it is the air filter...because nothing is wrong like i dont have any problems i just though that maybe everyone else's does this but apparently not. any way thanks for the help appreciate it!
