I probably should. I have owned the wheelset for many years (much longer than three years, which is the standard Shimano warranty length on Dura-Ace components). The torque wrench I used is a HarborFreight wrench, of which spec I am not so certain. I just might talk to Shimano to at least see what they say. I use the same wrench on other wheelsets, but because the freehubs are all either made of steel or titanium, no issues at all. The FH-7801's freehub is all aluminum.
