It would only be worth doing (and i can sell you my 40,000km old injectors within the month once i go FI) if:
You get a piggy back and get a tune
if you stock injectors are smaller than our 288cc ones or 330cc (cant remember exactly)
if you have other mods (plenum spacer, pod, exhaust etc) that are increasing the air into engine and thus your engine needing more fuel (u will need a dyno to see how rich you are..)
