This applies to any car that has an aftermarket tune:
California State’s Smog Check program will change from July 19th for the worse because “vehicles with software not provided by the original equipment manufacturer or approved through a California Air Resources Board executive order will fail the Smog Check.”
In other words, If you have a tune from any supplier without an executive order, you will fail your smog check.
You will have to put your original tune back into the ECU then drive for 600+ miles to get all the smog checks back working.
(usually it's the cat that takes so long for the ECU to read its on). My silver took 900 miles until it passed.
