Passing Smog in SoCal with mods

Regardless, if EPA or CARB actually was only motivated by wanting cleaner air (which btw I’m all for personally), and not some socialist political agenda to push us away from POVs, then the ONLY thing that matters would be a sniffer test. After all, the only thing that hurts the environment is the tailpipe emissions, not the computer programming in your ecu. That would be a common sense practical application of clean air laws.

And even if there were some kind of surcharge, that would be fine too. My car still has cats and I run e85. Probably runs cleaner than a stock z.
