The IVECO Curry engines are supposed to run up to 115% only if the unloader is running. 115% is the point where the fuel gets derated. If the unloader is not running then it should only go to about 105% before derate occurs. Also if the engine water temp hits 105 degrees C, then the engine begins a slow derate as temp increases. At something around 125 degrees C you only get 50% engine torque due to the temperture derate. There have been several guys on the NH page disappointed by the CR970 in wheat also. On the other hand, they really eat beans.
