Turbo question
Coming home tonight I gave it a little bit of throttle and got off of it right away and heard the turbo barking a little bit like it was releasing the presure. I was able to duplicate this. It would bark 3-4 time and sound like a whoomp whoomp sound. Is this normal?

Thanks guys. Could a dirty egr valve cause this also. I have yet to pull it and clean it. Truck has 78000 miles on it now. I plan on doing it some time this weekend when I change my fuel filters out.

Got the fuel filters replaced today and I also cleaned the egr valve. It wasnt too bad. I was suprised since this is its first cleaning with 78000 on it. I seem to have a little bit better power now. It ran a little rough until it warmed up and then smoothed out. I did notice I was still getting a turbo fart from time to time but not bad. I have only ever noticed it one time when I was hauling a heavy load. Maybe I just never paid attention since the radio is always cranking. By the way the egr cleaning was a piece of cake. I accidently drop one of the screws and had to use a magnet to fish it out. No biggie. Hardest thing was figuring out how to turn it to get some rope down the bolt holes.
