Rear O2 sensor removal with U7198 v2.13

[nsmcc]

Predator U7198 with v2.13 performance tune installed. I have a 99 corvette that i recently put LT headers with hi-flow cats on. After about a week I did get a P0430 code. With the older version I understand that the rear O2 sensors can be removed. How is this done? The only place that code shows up is in the COT menu. In the O2 sensor menu there are a bunch of P codes but not the 0430. Does turning off the P0420-0430 codes in the COT menu the correct way? How will this effect emission testing?

Thanks

yes, the 420-430 codes in the COT menu are the ones... that is all the cat. converter stuff in there... those are the two cat codes and then the COT itself...
