300C 2006 5.7 Raising Shift points

[Nazab]

Have just bought my predator and installed 91 CAI tune on my car. Results are quite fine and I am happy. Just need the following advise on the Quick Adjust options.
1) Shift Firmness . Is it only 1 option , or pushing this button several times makes any difference ?
2) Shift Points. Raising shift points means the car will shift at 6000 RPM instead of 5500 RPM. Will this has any negative or risk of damage on the engine on the long term ? Chrysler reinforced the cranckshaft on the SRT to increase the RPM to 6400, so 6000 RPM for the 5.7L might be risky ??
3) I got with my Predator the 180 Tstat ... do I have to change that ? Why ? The car is running at normal temperature and no lights coming up or anything is wrong , so why do I need to change it ?

Thank you for answering all these points please..

Firmness only happens once, it is a pre set change.

Raising the shift points to 6K is not so bad, going higher may be risky.

No need to change if it is fine, but lowering the fan temps to match the stat will make things more efficient.
