I was just about to ask about this.. I recently reverted my car back to factory stock completely (even reinstalled the sound tube) with factory rom, after having been called in for a CA STAR smog station to renew my registration,. Barely passed. Then shortly after P0456 code pops up. Also, it has the idle dip on the original MY13 A01C rom. I never took it in to the dealership for the TSB. The stock tune on the early MY13 do really suck, relatively speaking.

I flashed an old tune I did back in 2015 for stock headers for shits and giggles and now it runs and idles much better. I was hoping this stage 1 tune could pass smog, but I guess not.
