>Anyone else seen factory setups with the HEGOs upstream of the turbine?

My Mazda 323GTX had it before the turbo. I have a TEC on the car, and have
had the sensor both before and after. It definitely does work better at Idle and
low speed light loads when before the turbo. But it overheats much sooner there
too, making tuning under boost more of a problem. I've recently gone to using
a UEGO for power tuning, so things are much easier now.
