That was my thought, i haven't really thought about it anymore, guess I'm used to hearing it and don't pay attention

i like my tb whistle well it came when i added the spacer, but do notice something louder at wot but its not a whistle its more like whine from the drivers side of the engine bay weird.

kind of off topic but while i was searching found this... I just got my cam installed yesterday and now it whistles? could it just need to be retuned? the truck drives fine other than it needs a retune.
