Having lived very near Death Valley, and been in Death Valley hundreds of times, especially in the summer, I can tell you the shade makes zero difference. Remember that it's almost entirely rocks, pebbles, and sand so the heat is stored from one day to the next. It doesn't get very much of an overnight reset like in temperate climates.
The hottest I ever experienced there was 124° on the big sign by the general store. The temperature sensor in my car said it was hotter, but I was mostly amazed that a Fiat and its tiny air conditioner was able to cope with 120's for a week.
