Trouble code P0430 U7145

[MattC74]

Hi, I have 07 Mustang GT running C&L racer CAI with a 91 oct custom race tune and PYPES axle back. I recently moved to a town that only offers 87 and 89 octane. Posted here before and was told to modify global spark -5 degrees. Here recently I been getting the error code P0430. I plug in predator to clear code and sometimes it finds it and then sometimes it doesn't find it. After it clears, it comes back about 75-100 miles later. Any thoughts? On a separate note, shifting from 1st to 2nd the shift is hard. I read on here somewhere before that you can adjust the shift in the tune? if so, how do I do that?
Thanks

that code is due to a poorly functioning catalytic converter on the passenger side....

So doe this predator tuner support turning off the O2 sensors? Or are they turned off in my 91 bama race tune?

you would need to contact Bama about that, they would not turn it off unless you asked for that.

Thanks
