    Hey there,
    Sorry I've got a bad habit of not checking PM's! Thanks for the update. Funny you mentioned the wastegate line, I finally figured out mine would only do it with the wastegate needle valve I added completely shut. Thats a pretty thick hose, so I think getting a good bite on it with a regular hose clamp over such a small line/fitting made it whistle. I just threw a few wraps of electrical tape over the fittings so the line made a tighter fit, then 2 new clamps on it, and I've only noticed a different whistle once- which was the lower drivers intercooler side boot sliding off.
    Thanks again for following up Mark.

    Gorms,
    I thought that I would update things- I still have a whistle, but it's only done it twice, and it was a different pitch. I thought that I had two different sounds. I found that the first cylinder from the front of the truck had an exhaust leak. I replaced the gasket, and although the original one was still intact, you could see where exhaust was blowing by. Being thin metal, I assume that it vibrated when exhaust was whizzing past it. So far, all noises are gone. To sum that up, I replaced both flexible hoses in the boost line from the intake manifold to the wastegate, and the exhaust manifold gasket.

    Gorms,
    I didn't know if you had followed my post, so I thought that I would drop you a PM. I replaced the short flexible hose from the AFC housing to the hard wastegate line, and my whistle is gone. I have run the truck hard for three days now, and it hasn't done it once. The old hose had no holes, but I think that once it warmed up and got pliable, it was letting boost pressure whistle past the hard metal line. Either putting a new line on, tightening the clamps, or more likely both, cured it. I like .25 cent fixes...
    Blessings,
    Mark
