Crap, I'm not sure what to think. That's a good theory though, NASA made that unit mistake and lost the Mars Climate Orbiter mission for pete's sake. For the Durango the 2nd edition User Guide says 110 but the 3rd edition Owner manual says 130. Both are the latest edition Chrysler offers currently. This sort of thing keeps me up at night.
I sent Chrysler customer service an email detailing this issue asking them to research with engineering for the true spec. Never gonna happen but worth a shot.
UPDATE: Milous stated in another thread the Factory Service Manual says 100 ft*lbs +/- 15
