They don't start running that rich at all. Stock files vary from 12.4-12.2 when they enter PE mode and gradually lower a max of -3 by the end of 24 seconds in PE mode....given it's a stock car, the most it'll probably lower on the AFR will be around 2.
They don't run rich at all really if you think about it.
