Is a BOV the answer?

I have a friend with an '07 5.9 with a 66 that barks all the time, is a blow off valve the answer or is something else going on that we're missing........

what is the cause of barking anyways.......is that the compressor stalling out when snapping off the throttle?

The bark is a result of the compressed air going out of the turbo the wrong way

So a blow off valve would remedy the tendency for that to happen it would seem........

but the operation of a diesel with no air valve like a gaspot, shouldn't have this happen or even need a BOV?

My SPS 66 barks ALL the time when I back off suddenly and it use to do it when my tranny was slipping all the time, but since I put the new tranny in a year ago it only rarely does it. Personally unless its constantly doing it as you are driving down the highway i wouldnt worry about it. If you are contact II and i would talk to Brady, he should be able to help you out.

i dont think its needed. i have barked my turbo 100 times and yet to have any damage. i asked about this a while ago and for the most part everyone said its fine the way it is

Before you invest in a BOV, search my name and BOV. You'll find some reading about your exact application...

I can never bark mine unless i get in it and in the middle of a WOT I just stop then it barks.
