They now count the amount of readiness tests and can check if they go automatically to "pass".

They also now monitor live data while the car is running and compare it to manufacturer supplied data to look for any variances.

If you live in a CA compliant state (I think there is 15 states now?) and you drive a 2001+ vehicle you get to swap everything back to stock every 2 years now

This is good (but crappy) information. Do you know which states are on that list? M guess is that Utah is NOT, as we tend to be at the back-of-the-line on these sorts of things.
