What HP Tune to run?

The lower tunes do not improve fuel mileage from what I understand and personal experience. This has been true on all of the chips out there.

Agreed, but what the common every day person would like to run is not the max hp program available. The 80+100 tunes have better throttle response than stock. Agreed also that the max hp program is going to be even be bettr than this.
Problems with your tranny? Have you put it back to stock to see if it does it there too? Or like you said ford's "updates"?

the issue is at all levels but most noticeable at the highest tune. What I do is disconnect both battery cables and then the "intelligent" POS resets and all is good for a while. I think the way to go on this thing is an engine and tranny tune. The learning capability of these things seems to be an issue. This is my first auto in a diesel and I am not impressed. I do drive in flat and then mountainous terrain though so it is probably partially my driving habits too. With my 6 speed manual this was never an issue.

As for the tunes, I found the highest was better than the stock, economy, towing and the first power setting. I tried all of them on a 10 hour round trip drive I was doing over and over and I would switch each time I went. for me it is either stock or the top tune it came with. The others just did not seem to do much on mileage which is why I bought it to begin with.

Jason,

What is the current calibration version you're running? We have an update coming out in a couple days that helps address some of those shifting issues and seems to be a bit better on economy as well.

Bill,

Once again I am on the road and will have to look when I get home.

I hope you are feeling better.

Jason.

Bill,

I am on calibration 1.2.681. The tranny shift issue is not as bad as it was since it only happened once since the latest updates and it was not as bad as we have discussed in the past. Not even close but still there a little bit. Let me know when the update is available and I will try it out.

I run mine on level 4 all of the time. Even when I have a load. Just have to watch your EGT's going up hill. Still would like to see if removing the DPF would help with lowering the EGT's or allow for a higher tune because of the lower temps like others have discussed in other forums.

Yes, I know it is not "legal" but damn I miss the smell of exhaust.
