For my car, 1.5L 89 Honda Civic wagon, I saw a sample of Fuel map of my car, It seems that we can fool ECU to think that " Lighter load" by offset MAP sensor resistor value by resistor. It will offset fuel map easily too.
Of course, If we can change ECU fuel map easily, It is a better choice, We can fine tune is for best fuel map for fuel economy VS power.
Both Map or Atmospheric sesor mod are dirt cheap, below $1, ECU fuel map modify cost more money and it needs time to learn this editing program, That fuel map.... better but a lots harder...
