Scott,what about the "easy tune" it sounds a little more my style. The one I have seems to me to really overfuel.(TOO much smoke) The tranny shifts into 5th around 50mph and 1500rpm it lugs hard,and EGT's run hot until it hits 1800rpm unless I really baby it along. EGT's run about 1100 to nearly 1300 then drop back,and that is not pushing on it.

Did you install a dpf delete pipe or full turbo back exhaust.

I believe it is the race tune. 80,120,175,250?? I was wandering about their "EASY tune" can you tell me anything about it?
Oh BTW I usually run on the MILD setting,and there is still too much smoke. I know it needs to smoke a little,but not a black CLOUD behind me when i'm not WOT.

Man,thats what mine gets workin. I do alot of 1 to 5 mile runs while doing my farm work everyday. Everyone that has one around here that has done the dpf delete is getting 16-20mpg. I try not to drive mine like I stole it,but getting out of a manual trans into an auto it is REALLY hard not to.
