Turbo whistle in new 06??

[DZLROKET]

With 4500 miles I am just now hearing the turbo spin down when I take my foot off the go peddle. Never heard it before??? Normal as truck breaks in??

Hmmm. I can hear mine though it isnt too loud. Make sure your intake piping from the air filter didnt fall off. Either that or you never paid attention before and you heard it once so now your listening. Thats about all I can think of.
