Tow vehicle!
The Ford dealer "re-flashed" my 2003, F-350 with the 6.0 diesel. It ran fine when I took it in for an oil change and the recall update. Now it runs terrible, with or without my Banks system plugged in. At partial throttle, it "barks", the wast-gate dumps the excess pressure built by the turbo. The dealer and my mechanic are trying to fix it.
Have any of you experienced this?
If I upgraded, what engines should I avoid (besides the 6.4L)?
