I just installed the O2 sensor removal kit ($40 from Hall's) and immediately noticed a difference. It removes the O2 sensor and includes a plug for the wiring harness that puts the ECU into "race" mode, richening up the fuel mixture, among other things. So far, all I've done is idle it in the garage.

-idles much higher, had to turn it down

-idles much smoother, 1650 rpm +/- 50 (it used to vary by several hundred rpm)

-starts easier

I'm going to take it out on a quick ride and report back!
