Terminator X with only one O2 sensor?

[dontlifttoshift]

One O2 is fine. I put a bung in each exhaust pipe. If the car ever goes on a dyno they will want to hook up their own wideband. If you ever have a problem it can be helpful to swap the O2 from side to side. If you want to be really fancy you run the car and leave the O2 on which ever bank tends to run leaner.
