...not really the best idea to run no upstream o2 sensor, while stock.

This is your a/f sensor (air fuel).

Without it installed the engine runs rich. Which reduces power, and money in your pocket.

The reason people remove the stock a/f on boosted cars, is that they're running aftermarket tuning ecus, with a stand alone, high quality, wideband a/f sensor.

.......

As for the bung hole on your header

If its placed on a single runner, this is where you mount the OEM a/f, if you're running a dual a/f system (usually for a piggyback ecu)

The original bung hole, which is usually below the header collector, is where you run the high quality aftermarket a/f. This is so it can collect data from all four cylinders, regarding the air, fuel mix.
