The topic pretty much says everything. I am going turbo and I need to know where the best place to put the sensor would be for the most accurate reading during tuning. Before the cat or after? Thanks guys.

thats way to close to the head, the wideband sensor would get killed there very fast because of the high temperatures in that area. wideband sensors should sit in the downpipe, not too close to the turbo!!

That location is best used for an EGT gauge not a wideband O2, there is excessive heat before the turbo and would fry an O2 sensor in no time. Usually a good spot for a wideband is near the primary stock O2 sensor location (usually in the downpipe) or just after the downpipe. You don't want your wideband sensor located anywhere after a CAT being that the CAT will cause a leaner reading than what is coming direct out of the engine.
