I'm in Salt Lake City. At an HPDE at Miller Motorsports Park (4400 ft altitude), my car would hit limp mode at about minute 3-4 of each session if I drove hard. The car was stock on stock tires. Most reports from low altitude tracks were saying I would probably hit limp mode towards the end of the run if I kept on it, so I assume the altutude makes it considerably harder on the car to manage heat well.

That said, I've never hit limp mode on the street.

It looks like you're at 5400 ft altitude, so it's a little worse but similar to what I see here. You're also only making ~80-85% of the power you would make at sea level.
