I need to do the same on my SRW '08.
From the research that I have done you need to get rid of your DPF and get a custom tune.

wheelhopper is right, ditch the dpf and get some custom tunes. Spartan Diesel Tech is claiming 21 mpg with there dpf delete, and custom tunes.

to the site.Yep the filter delete and custom tunes is the only way I have heard that high mpg can be had with a 6.4
