You can torque dry or lubricated, but the torquing specs are different.
If the manual is unclear, check a source that gives dry and lubricated
torquing specs for the bolt size and grade. Yes, you can over-torque
if you lubricate and torque to the dry spec.
BTW, a good reference source on this subject is Carroll Smith's NUTS,
BOLTS, FASTENERS AND PLUMBING HANDBOOK. Smith's writing style can be
a bit overbearing at times, but he knows his stuff.
