ect vs normal auto mode.

Hi everyone, i am new to computers so i hope forgive any errors. i just bought a 2016 4cyl 4by 4 automatic base s model no rear seats. i took it out on the interstate in ect power mode and was much better and did not seem to look for correct gears near as much, according to the tachometer at 65mph 2200rpms is this acceptable? also i tried running with out air conditioning and i notice seems like much more power this way, does anyone else experience this and this is my first truck since 1992, thanks for any comments!
