Before!

I would say "of course" but i don't want to sound snotty.

Lamda sensor is inserted right after header, about 3" before the cat inlet.
We also put a pyrometer sensor there, to measure exhasut temperatures entering the cat.

 

Sorry, that was directed at Hymee. I figured you would have done it before the cat, but since Hymee is doing a one-off dyno run, it's common practice (In OZ at least) to shove a sensor in the tailpipe and "correct" the readings later.

"Mine" was measured with a wideband O2 sensor stuck up the exhaust pipe as per "usual" chassis dynoing. We had not hooked into the ODBII port to read the ECU's inputs.

Cheers,
Hymee

 

See canzoomer? So his readings aren't really comparable with yours. His would be ?leaner? than true.

Indeed. Depending on what kind fo job the cat does in scrubbing.

Also, some fuel probably gets burned up as well.
