I understand that if you replace 17# injectors (or whatever comes in 98 svt's) with the green 19# injectors you have to let the computer know. This can be done with a chip. My question is how is this done with a chip?

Is it done by adjusting the air/fuel curves? Or is there some type of memory circuit that stores the injector size? Any help would be much appreciated.
