2g maf

I have the 1990 galant gs w/ the dohc 4g63 and the 5spd. I have tried to research this but im not sure im understanding it. I want to change to a 2g maf, would i need just that and the 2g injectors if i am keeping in NA? or would i need a programmer of some sort? I hear that it increases air flow a lot and i need a new sensor anyway so if that will work then i would rather do that. I would like to eventually go turbo but i cant afford it right now so i plan to do all the less expensive things.Thanks.

dont worry about it until you go turbo. you need the sensor, plug and part of the harness to rewire your current sensor into the 2g sensor. you can do it now and see little gains from it
