My truck is down AGAIN I can't believe it . 2 weeks ago they replaced what I think was called the front center turbo. Drove it about about 4 days and it started making a new noise and I had a loss of power ,black smoke cloud everytime it made this noise. I even thought the tranny was going cause it was reeving so high and not wanting to shift. I went to the dealer last Tuesday on Friday I called they said some sensor was replaced they would take it for one more test drive and would call me back. 1 1/2 hrs later the service mgr called to say he took it out and it drove fine but on his return trip he had the problem I had. He said it was under boost the noise I heard was the exhaust being forced back thru the air Intake. He said he has only seen this problem twice before. I believe he said they would replace the Turbo housing assembly its still at the dealer as I write this. This last incident has pushed me over the line I went and ordered a new Ford F 350 Lariate with the 6.2 gas I can't say how much I love my Harley but I can't count on it anymore. When in about 18,000 mi I have to pay for this annoying stuff I don't know the answer to what choice do I have.. I will most certainly miss this forum when I switch over to the other fuel you diesel guys are the best......................
