09 3500 Mileage tune

[ogden08]

I am currently working on a 2009 3500 and am trying to get a mileage tune. I know I need to log my cruising area and adjust the tables in that range. Is anyone willing to help me with what I might need to adjust or just give me some pointers. I am def new to tuning so any help would be appreciated. Thanks

Just took a quick look at the tune. As far as mileage only goes you have a good start. Some quick feedback: for the sake of drive ability I would recommend smoothing out your duration table on the top end. You can leave idle timing alone. I don't like running that much timing at higher load and lower RPM. You might be able to get away with a tiny bit timing in parts of the higher RPM cruise and tip-in range but would have to log it to see where you are at first.
