Chip is used to control timing and size injectors.
The mass airflow sensors on our cars reads the amount of air and if the injectors are large enough it automatically adds the correct amount of fuel. Simple enough.
No fuel trickery required and thats the beauty of a MAF.
Of course if your turbo is swallowing a lot of air it may exceed the stock maf capability like mine did, then you get a bigger one and use the flow data to program the chip so the computer knows how to read it. It isn't necessary to calibrate the injectors to the maf since the computer does it all. If it knows how to read the maf signal and it knows its injector size it will add the correct amount of fuel...or close to it. Fine tuning is necessary.
