Let's talk tunes and smog in CA...
Is there anyone out there who has catless headers, hasn't relocated the o2 sensors to section 1, AND successfully passed CA smog with only a tune?
Disregard the sniffer test as it no longer applies in CA, but theoretically you would need a tune that both turns down the o2 sensors while still keeping them in a ready state to pass the OBD2 test. I know Evolve and some others are supposed to be able to do this, but I'm hoping to get some conclusive feedback from you guys.
The tune that can do this gets my money
