If this tune dramatically increases time between active regens (which it seems like it may, if the ecodiesel forums are indicators) and the vehicle will still pass state emission testing, both GDE and Ford will get a sale. My required driving makes owning a diesel imprudent in the mean time. Oil life extension is a nice benefit, but honestly if the only nuisance of diesel ownership was more frequent oil changes I wouldn't have given it a second thought. I can accept potential loss of engine warranty with a good engine.
If you can accept a void engine warranty then delete it. Plenty already have. Not any members on here, but check out the 3.0L Powerstroke group on Facebook.
What state do you live in? Pretty much any state other than CA, you really have no issues. Maybe a few really liberal ones.
