The engine being balanced internally has nothing to do with vibrations. And their having logged "250,000 collective miles" means nothing...they might have a point if they had logged that many miles on one car, but the harmonic vibrations that the stock crank pulley removes from the system may cause premature failure of the main crank bearings and other hard to replace internal parts if you remove the stock pulley. Its all a question of how much risk do you want to take by installing the part? Ford didn't include a dampner in the stock pulley for no reason...automakers don't install unnecessary parts on cars because even the tiniest of savings (less than a cent even) will add up when you're building millions of cars.
