Yes...use the O2 sensor.
Under load and boost, it's ignored...but any ther time, such as part throttle cruising, highway driving, etc...you'll need it for any fuel economy.
Just weld a bung into the downpipe, at least ~12" from the turbine.
Put an extra one further downstream for the wideband, to extend the sensors life.
