I don't own a ultragauge, nor do I own a car that can work with one. How quick does your AFR charge, and are you running a wideband oxygen sensor? I watch the oxygen sensor directly through a pin on my car's diagnostic connector, but mine is a narrowband oxygen sensor.

The back cat, I fixed the exhaust leak and the car wouldn't move under its own power, so I undid the exhaust leak and my power came right back.

Secondary o2 sensor is fine, there is just too much exhaust flow now due to no back pressure from the #2 cat because I hollowed it out. So I had to bring the o2 sensor away from the exhaust flow, spark plug anti-fouler worked perfect for this.

It was a long, gas wasting experience.
