I have a Hypertech tuner and have repeatedly gotten P0430 code but have been able to clear them but not anymore. When I call firestone they told me it was a bank 2 catalytic converter issue. Anyone throw this code and how did they fix it?

Unfortunately I have 105k now. No rotten egg smell either but sluggish on interstate driving. I did return it to factory setting on Hypertech tuner. I threw the code more when I had the W.O.T. removed. Any particular aftermarket cat converter to use?

I think i got this code and it turned out to be the front most drive side sensor. I knew because it looked like a rock hit it and it was bent in half.
