Then there are the expensive oxygen sensors.

I'm pretty sure it's been tested and proving that in LB the cylinder / exhaust temps are actually lower then when running at stoich afr's.
I can see his point though on EoC and P&G being more of a benefit than LB is.
In my case I am really starting to see the benefit to taller gearing *which I do not have yet*
