Hydra tunes differences

What are the differences between the different tunes? Shift points? Or anything else?

Example, there is a 80hp tow, 80hp daily driver, and 80hp performance.
Obviously the tow tunes are for towing, but what is the difference between DD and performance.

I suppose my real question is which tune is best for what situation?

TIA

Shift points.

80 tow will shift later.
Daily driver shifts sooner. And performance is somewhere in the middle.

Daily driver and performance will net good mileage.

You know, sometimes I've wondered the same.
Though I don't recall having a tow tune with a higher hp like that.
But I've noticed I'll get way more smoke in the daily tunes vs the performance tunes.

I think the performance tune will dump more fuel at lower rpm and be more prime than the DD. but i might be way off.
