Why do you want to test at higher than rated speed? Output usually drops dramatically above rated speed and reaches zero at high-idle which is usually only a little above rated speed. (If the governor is electronic, high-idle will be the same as rated speed)

Use T mode if you want to test the engine at various loads. Once the load exceeds the rated output, the speed will begin to drop.
