To be honest all I really pay attention to is shift fallback. Currently it has a 9.5 ATI. Falls back to 6200-6300 depending on temp and shift point. It's in high gear under 5 seconds. The Ultimate 9.5 is similar though fallback is about 200 rpm lower. ET/mph is about the same. 31.5 M/T's go thru @7250@149. Shift points from 6700-7200 really don't change anything.
