The EGTs do a fine job. I agree the O2s accuracy depends of the model/ manufacturer used.
There are two basic O2 sensors out there: The Bosch Sensor and the NTK sensor.
The Bosch sensor gives a "general" air/fuel ratio.
The NTK sensor reads ACCURATELY from a 6-1 ACTUAL a/f ratio to several numbers higher than stoich (14.7-1) air/fuel ratios.
Maybe not important for drag strip usage but on a Bonneville 5 mile run very important, or a road race vehicle if EFI.
Or a true street vehicle.
Not sure what a SF bench uses.
So if you are trying to tune your STREET Bathtub intake and carb set-up, I would always use a NTK sensor system.
