You only need to change your injectors if you have a mapped ECU and your injectors are open for 100ms or more on full throttle. If you put high flow ones on and didn't get a mappable ECU your car would run permanantly rich because your simply putting more fuel in with no extra air. The better option is to use 8 injectors but each one injectin ghalf the amount of fuel. That way, you will get a better air/fuel mix and more power/economy. Similar to the 8 valve - 16 valve.
