This comment is a generalization based upon my own experience. Your mileage may vary. If you are going to use any of the portable impact guns for removing your lug nuts, I highly suggest in the comfort and time of your own work space that you loosen them, and torque them to 450. I suggest that in lieu of finding out that some gorilla with a 1 inch impact running off 150psi air has hammered them on. If the lugs have been tightened like that, the electric impact may not take them off. However, if they have been torqued properly your chances of success are much higher.

We got a pneumatic impact, with 3k/lbs reverse torque, and it has 3 torque settings. We also got the 100-600 lbs torque wrench to be able to set correct torque of 450-475. I'm going to reset all of my lugs once we get home, because the shop that installed the tag wheel 3 years ago, also installed all the other wheels when I replaced all the tires.  Thank you for your advice.
