That is very interesting. Do you have any more information on that "factory breakin programming"? I know the manual said to expect mileage and performance to increase over the first 10k miles but I did not know that was a programming issue. I just figured it was a mechanical break in. Where did you get that information?
Thanks

I have not heard anyone else say that either. Not that I don't beleive you but what do you have that backs that up or supports it? I think it would be an interesting read. Learn something new every day

i have no way to prove it...it just what i have read from mostly the hemi ram forums and from driving my mothers 06 CTD ram mega cab...it not a huge difference in power or mileage...but it IS noticable

I have nearly 17000 on mine and mileage still sucks, I am going to get a programmer to see if that helps.

RE: new 6.7 diesel mpg problem

if your after mileage... hold off until I do a "no programmer run" in my mpg testing... should be coming up soon. I'm going to hate driving it that way as power will go way down but I need to do it. also, I'm planning on doing a #1 std program test on the TST as well. It's been suggested that it is the best for mileage. I would tend to dis-agree at this point, I never got anything better than high 17's with it, now on 2/2/e, I'm into the 18's... with more power on top of it.
