I have an 04 and whenever I accelerate from a dead stop, I hear a loud whistling noise. (tea kettle sound) It almost sounds like a loose valve. I took it to the dealer and they said that they are aware of the sound (especially with A/C on). They said that there is a service bulletin but they do not have a fix. That seems to be the answer of choice when they don't have an answer. That makes you mad when you pay $50k+ for a truck and they say they don't have a fix yet!
