Wow hmmm thats interesting. I will talk to my smog tech tomorrow . Unless the Tunes do not effect emissioms at which point i eat crow .lol I could be wrong. Perhaps some of the Tunes are just mild enough not to effect emissions.
If so I humbly accept your proof.
It's a topic that interest me, because I plan to go with my DHM360R turbo kit w/aux fuel and pass for it's first mandated inspection in 2020 unless I get popped again and have to pay the CA State ref a visit again. My car is a '14, so I'll be visited CA smog inspection before many others who aren't radically modified in terms of emissions components. My car will pass OBDII no problem, it's the visual inspection that will be the determining factor in my case.
My belief is that as long as the tunes do not disable any of the IM readiness monitors and has no check engine codes, the car should pass. Most of the tuning done to maps are under boost conditions. Most tuners don't mess with off boost tune parameters without risking poor mileage and emissions. Rolling dyno test sessions are never under boost conditions.
My engine compartment looks stockish, but there's a big turbo, ST200 intake, RAMAIR crossover pipe and aux fuel in there.
