My guess is your friend is confusing CO and HC. The number you posted looks
more like HC. HC is measured in PPM. CO is measured in percent.
Catalytic converters do wear out, and 180k is a lot of miles. It's been my
experience that HC numbers are usually the first to get up over the pass/fail
cutoff as the cat gets older. Nothing scientific about my findings, that just
seems to be the way it goes most of the time.
O2 sensor failure is also pretty common. A good one will switch quickly between
0 and 5 volts.
Messing with octane *may* help *slightly* with a NOx problem, but will be no
help to you if you indeed have a HC problem.
A fresh tune couldn't hurt.

Re: CA Smog help
It turns out my O2 sensor was busted. The ceramic was broken and the wires
