I’ve done at least 100 AutoXs on the ~440 RWHP my Z06 used to have. I only got to AutoX is once after getting the 427 and 600 RWHP all finished up before heading out here to Durka, but it wasn’t a “problem.” You only have as much power as you ask for with your right foot. I was able to use WOT a good bit on a pretty tight course.
