Potentially big time smog issue?
The bad news hit today however when I tried to pass smog here in GA. Background on the car is it has catless downpipes and a stage 2 tune, and was advertised and sold by the dealer in CA this way, smog was not previously an issue being new enough not to require passing smog in Cali as well.
Today I was told it doesn't pass as the O2 Heater and Sensors show inconclusive. After a little bit of digging and chatting w/the previous owner, as well as the shop that tuned it, it's bc they turned off the O2 sensors when doing the tune. I was told if I flashed back to factory tune, that would essentially turn them back on, and I could then pass smog, then buy a module from them to tune it myself. However, it got me thinking that if I flashed back to stock tune, wouldn't that proceed to throw a bunch of other codes then due to missing the cats?
Trying to figure out my best path forward, I believe it's very much against the law for the dealer to sell a car that won't pass smog, so I do have that in my back pocket. However, I'm also hoping it won't devolve into legal threats and actions that could in the very worst case scenario, end up w/me sending the car back across the country to them?
Thoughts/input welcomed and appreciated, thanks in advance.

If your tuner is asking money for a handheld you might as well hit up ptg for a tune because he can flash firmwares if you need to roll back and you can use a laptop to flash the car.. actually the first thing you need to do is get a stock file on and go from there. I would argue with the dealer to get the car stock tuned. Your lucky in my state you would get flagged and need to bring the car to a special inspection station and they would go through the whole car and see you missing cats and fine you.

However, if the car is sold and older than 4 years then it needs a valid smog certification. Not sure what year OP's car is, so if it's less than 4 years then yes, in California it wouldn't require a smog check, but since he is registering it in another state, that state dictates if it needs to be smog checked or not. Whatever happened in California is only valid in California.

I can probably get it flashed back to stock if I take it in to him, but there is indeed an open recall on my car that according to Geico is: RECALL #2020070001 CARB
I think monkeying with spacers on a stock tune may be my only option. Although the more drastic measures I'm considering include changing my address back to family in another county that doesn't require smog at all, it's a pain in and of itself.
I did give the dealer a call last night just to see what the reaction would be and it was a little better than expected. He essentially admitted to the fact that they knew smog could be an issue, and was hoping to sell this to someone out of state that wouldn't be impacted. I told him very firmly if at any point in their ad or through our exchange I had known it would not pass smog, I would not have pulled the trigger. No talk of a solution but he said he'd call up the shop that tuned it and see what their thoughts were and get back to me today.
