Naw, I run mine open most of the time at the same location. I think your passenger cat is just toast. You can swap the rear 02's and see if the code changes, but it's most likely the cat.

Swap sensors... if you pop a P0420 then it's the sensor (code followed sensor)... if it still stays P0430 then it's likely a failing cat.... a bad cat can cause performance loss (if it's clogged)
