Changes in aircraft engine power is a common feature that aims to change engine parameters in exchange for benefits such as higher takeoff and climb performance or higher maximum takeoff weight that can be translated into higher payload and/or higher fuel load which in turn translates into greater autonomy on specific routes.

The technique will be used by Azul in the engines of the Airbus A320neo. In fact, Gol also uses the technique. Modification packages are intended for operation on shorter tracks.
Fernando Kehl, Airbus Fleet Manager at Azul, said the gain from today's shift packages would be significant in terms of maximum power, but longer routes would suffer.
“We've identified that if we move to 29,000 pounds of thrust, we'll gain an extreme advantage in the Santos Dumont operation, and we're making this modification now on some key planes,” Kehl said.
CFM, which produces the engines, will make available the new power that respects the limits of the engines, in order to maintain the reliability of the apparatus, increasing the maximum thrust from 27 thousand pounds to 29 thousand pounds.
This is achieved through a plug called "thrust rating plug" which is nothing more than a jumper plug whose containing a combination of pins ("jumpers") that tell the motor what power it should use.
It is also necessary for the aircraft manufacturer to provide certification for the aircraft to use this increased power. This usually consists of making available the AFM (Airplane Flight Manual) chapters referring to the new power and the performance software plug in that will allow the airline dispatch to make the performance calculations for each flight.
