Probably just the injectors. I can really hear mine when lightly accelerating at lower speeds.

add some 2cycle oil to you diesel, it will silence it up. 16oz per full tank, and some put 1oz per gallon.

Mine are really loud too, I used optilube over the winter when they were the loudest and it really helped mine out a bunch. :thumbsup:

My 07 5.9 does the same thing. I've been told by three diffrent techs that it's normal. The three 5.9s I test drove all did the same thing as well.
