You'll notice that if you're able to pull codes, the limp mode that comes up is generated from a Rail Pressure Plausibility issue. Some people run into it at 100%, some at less. There are a variety of factors that I've found that can make it more likely, such as higher ambient temps, car being cold and driving aggressively, and elevation (seems higher elevations make it more likely).
