Shift firmness and timing questions

I'm sure the f150 wont do that but I'm wondering what it shifts like at 25 and if it's advisable.
Secondly, the manual (which by the way is pretty vague) says you can bump up the timing for every octane number you go up. Does level 3 already advance the timing or can I bump it up a little since I run 92.

I have been running my shift firmness at 25 since I got the programmer and haven't noticed any problems, I think I read a lot of guys on F150online run theirs at 25 all the time.

Hey Buckeyes, thanks. How does it shift at +25?

The shifts feel 100 times better then they do at stock, it feels like the truck actually wants to move and that you are quick shifting a manual. It's awesome

I have read in other forums that the 3-4 shift should be set lower than the other shifts since that is the weakest link in our transmissions. I would think that would only apply if you are doing a lot of WOT runs. Maybe someone else here has more info on this.

I've only ever changed the 1-2 to 25 and left the others at 0.
