I was reading in the October 09 issue of Diesel Power about the new 6.7.
I have a few questions i thought I would bring here for discussion....
The first involves a section on 'Noise'
"...the engineers toggled the pilot injection on and off. With the system off, the 6.7L sounded like the first '94.5 7.3L Power Stroke, but with the injection turned on, it seemed much quieter than the current D-Max or Cummins."
How long, if at all, do you think it will take for us to be able to toggel this via a tuner? I really hope we can
Second, Fuel Economy:
"No figures were quoted, but we were told the new 6.7 will offer a substantial fuel economy increase over the 6.4L. The smaller
DPF on the 6.7 would indicate the new engine will use less fuel-economy killing active regeneration"
My question is, I know they will have the UREA but wouldn't a smaller DPF build up soot faster, thereby increasing
the times it will regen? Or is the UREA that good of a thing??
