I'm going to assume by "part throttle" you simply mean you are not accelerating, because diesel engines typically do not need throttles.
I also would not expect to get better mileage "leaning" the mixture at light loads because diesels always run lean; reducing the map at light load would simply reduce power forcing the driver to apply more fuel via the accelerator.
