[B]I got some black rays light weight lugs,(not cheap) and torqued them to 80lbs, then drove 60 miles and retorqued them again, no lock tight.

just a guess, but your problem is the lugs probably did not have the proper taper.
just thread size, pitch, and dimeter is not enough. must have the correct taper. lug nutz are not just generic nutz.

I would venture to guess the coefficient of friction at the threads and under the nut head is different with these lug nuts than it is for the stock chrome finish. The torque setting and coefficient of friction provides a certain amount of preload so that the resulting friction force at the threads and under the head prevents the nut from backing out.
It's also possible the seating ball shape may not match the wheels. When the wheel rotates and the nuts are cyclicly loaded, the wrong contour seat can allow the nut to back out. Somewhat like a spinning coin, when it's nearly laying flat at the end of it's spin, you can see how the coin rotates as a result of the cycling contact.
You should never have to add loc-tite to the nuts. You should never add lubricant to the nuts for certain. The best thing you can do is use brake cleaner on the threads and in the nut to assure the threads are completely clean and dry. Also spray some on the tip of a towel and clean the seating surface on the wheels.

i don't think there is anything wrong with the lug nuts. Check your hubcentric ring and be sure it's not smashed or bent or messed up. Be sure the wheel is flush against the mounting surface and as mentioned above, be sure the wheel is torqued in the air, not on the ground.
