I occasionally have some fun with my base model TL coming home after a late night shift, and sometimes I'll even try a 0-60 run haha.
One night I came up to the usual spot, and I held the revs up to around 2k to launch, and gate shifted the 1-2 making sure it went up to 6500rpm on first. I achieved a time of 5.78 seconds to 60 according to my obd2 scanner app, which was really surprising to me, considering the times I had seen online.
Some factors to consider: I weigh around 120lbs, was low on fuel for that run, and the spare tire was out of the car as well.
So to get to the point, should I trust my obd2 scanners' readings? Is this something a base model TL can really do? The scanner uses gps data if that means anything.

Can't say, other than fill the tank, put the spare back in, have a big dinner and try again.
