How can I change the torque to make a boost effect?

I made it in C++.

Added a second engine (turbo one) to the actor and then swaped.

In the Class Header

/** Turbo Engine **/
UPROPERTY(EditAnywhere, Category = Turbo)
FVehicleEngineData TurboEngineData;
  
/** Activate Turbo **/
UFUNCTION(BlueprintCallable, Category = Turbo)
void ToggleTurbo(bool b);

Implementation

void ABaseVehicle::ToggleTurbo(bool b)
{
  UWheeledVehicleMovementComponent4W* Vehicle4W = CastChecked<class UWheeledVehicleMovementComponent4W>(VehicleMovement);
  
  if (b)
    Vehicle4W->UpdateEngineSetup(TurboEngineData);
  else
    Vehicle4W->UpdateEngineSetup(Vehicle4W->EngineSetup);
}
