I don't know that I've seen 17" mentioned anywere but SE and RT according to the owners manual are 100ft pounds but on an earlier post this came up from a very reliable source.
100 is about right for 1/2" or 12mm studs
110 is correct for the 14mm studs used on all challengers.
listen to the chrysler engineers on this one. 110 ft/lbs is best
