U7135 2010 Charger R/T Shift points and tire size

[sglucas]

I have a 2010 Charger R/T with the Road and Track pack. V.9r27 I have added my tire size to the Predator, it says it has been added but when i check back the size is blank and it reads no size added. What gives? Also I have changed the transmission firmness to increased but it does not let me set at what RPM I want it shifted at. Is this normal? Thanks to anyone that can help.

Firmness is a global change.
Tire size stays once you set it, but willnot show your setting each time you go back to look.
