Dynojet - 3 months old - all new equipment. This was on two different
dyno's (both the same) and on the same vehicles.

Again, all factory vehicles do indeed run at 14.7:1. This is a federal
mandate. The narrow-band O2 sensors ONLY function is to indicate leaner
or richer than the desired 14.7 to 1 ratio. Buy an A/F gauge and you
can watch it visually. Catalytic converter functionality would be
severely degraded if this were not the case. In fact, it would melt
down also at least on the rich side of stoich.
At WOT, mine runs between 12.0-12.7 per the factory calibration. This
was verified w/a wide-band O2 sensor.
Not doubting your results - just stating fact. Maybe its your test
equipment - what you using? If dyno - whats their equipment? How old
are their wide-band sensors? Have them do a free-air, or immerse in a
stream of known gas like propane.
