The dry sump first oil change is 500 miles due to seals leaching causing the oil to foam. Not only did they do that, they rev limited the engine to 4500 rpm's until after 500 miles for break in. After 500 miles, the rev's are limited until the car water temp warms up. They have a secondary redline on the tach that displays this.
