Check your DPF regeneration PID. If it is regenerating (active), it's normal.

Yes... I recall noticing that a 6.4L during regen will make a turbo flutter sound similar to the 6.0L during sudden deceleration. Good call Alex!

i'll check that monday,see if it's in regen and update

Or have a look at TSB 07-04-11. It will give you characteristics to help you determine if it is regenerating without having to hook up your IDS.

I thought I'd resurrect this post to show you guys something wonderful.

The brand new 6.4 reflash finally has an indicator in the dash to let the customer know when they are in regen!!!! /forums/images/%%GRAEMLIN_URL%%/cheers.gif /forums/images/%%GRAEMLIN_URL%%/notworthy.gif /forums/images/%%GRAEMLIN_URL%%/rockon.gif /forums/images/%%GRAEMLIN_URL%%/cheers.gif
