Seems like everything is in order except the heater correction. Bank 1 is running 25% lower than bank 2. I just replaced the O2 sensor less than two tanks of gas ago. Is it possible the additional heat from the turbo, which is only a foot away (physical distance, flow piping its probably 18"), is causing the drop in heater temp on that side?

In don't think so -- that's all based on a wire's voltage for a wire dedicated to warming up the sensor.

The heat could be killing the wire itself tho and causing misreads -- what are the values for each bank? Lower values mean the sensor is getting up to temp quickly (unless its a misread), higher values mean it can't maintain operating temps.

Are the O2 voltages and AFR'd different for each bank too?
