The sensor has to be in front of the cats. No question, no way around that.
Check that first and I bet itmight be your problem.
The factory put the front O2 sensors for the PCM in the drivers side manifold and in the passenger side head pipe just below the manifold. So if your long tubes have bungs I am betting your factory O2 sensors are now mounted in those header bungs. The rear O2sensors from the factory are for emissions only and you can not put your wideband sensor right there because it will not read correctly and does not heat up fast enough when placed that far from the header. So if your installer just stuck the wideband sensorin the rear O2 bungs in the cats, because you have the rear sensors turned off in the tune then he did an improper installation of the O2 sensor for your wideband. Have them put an eztra stainless bung in your header for 50 bucks - move the sensor there and your done.
