So there is no way to adjust shift points for a automatic transmission? If your not in the throttle hard the car is in 4th gear by the time your up to 25-30 mph?

i have the predator u7194 im using on a 2011 ss camaro w/ automitic trans.
i would like to know how to adjust my shift points, specifically the skip shift from 1st to 4th.
also is there a tune i can use for 89 octane fuel? we dont have 91 octane in my area only 93
