If I set my 1" impact gun at low, it spins the nut on and stops at 300 ft lbs or so, particularly if you don't let it hammer more than once. If you are worried just loosen a few off and torque them again, paying attention to how hard they are to loosen.
Luvrbus: how often does a bus nut have to tighten the nuts on all 10 wheels at once on the same day?I have too many times seen tire shops put the nuts on with the 1" gun, then go around with the torque wrench set at 500 lbs and go click, click, and say they are torqued, when in fact they might have been tightened to 600 lbs or more, and the torque wrench for sure is going to go click, click. And when asked about it, say that they are doubled checking that they are tight enough. Sure they are: they are too tight!I do my own, one at a time, and they are done right.JC
