Azn is right, The ROW (rest of world) cars had different fuel/ignition maps then the US one's Giving the ROW more power. Changing the injectors of a NA is easy but its pointless unless for some reason your trying to get more fuel, which unless your getting more air in there is no point. Most of the high HP 951 guys change to bigger injectors because the stock ones just cant support the Fuel need for that HP level and will start to exceed the 80% duty cycle limit. AUH ae you trying to get more power from your 944???
