The point I would even consider close to lugging is when you are climbing a grade and it gets steep enough that more throttle gets you no more speed. Combine this with the second ingredient, too low rpm and you might get closer to lugging at rpm 's below 13-1500.

Throttle position would never be close to WOT.

In the old carbed days with specific volume accelerator pumps, it was much easier to "lug" and engine by flooring it at much to low speed in too high a gear. Now you have doubled or tripled the fuel mixture, way too rich, and you can do real damage.

With modern efi that is impossible.
