Looks like you've got your priorities all figured out and it's obvious you know what's going on. My previous posts really don't address your concerns do they?
Sorry if I possibly wasted your time.
Now it sounds like you DO want an E85 tune, as well as two others. I can't tell from your previous posts - do you actually tow? A towing tune is set up more to get things rolling from a stop or to bring things up to speed. You probably get a fall off in power at the higher speed end. And, if you tow, what is it that you tow? A big heavy horse trailer or a fishing boat?
If it's something lightweight, you probably don't want a tow tune at all.
