When you go with harder differential bushings there is always the potential for increased gear noise. I say increased because it was always there but your mushy stock bushings were insulating it. Right of the assembly line some rear ends are set up more "loose" than others so it can vary from car to car.
As has been mentioned, a fluid change and adding an additive can help. I would make sure your buddy has plenty of experience messing with gears in a IRS car before he goes in there.
