What HP Tune to run?

[jasfaa]

I run mine on the highest factory tune. Can't remember what that HP is anymore but it gives me the best performance as well as fuel mileage. (17 to 18 mpg on highway). My only issue has been tranny ones at this level. The electronics in the tranny seem to have an issue with this power level and make it shift funny even after the latest updates from Ford. not sure what to do about it but right now I am too busy to look into it further.
