How do I cure a lean condition?

Crap, I have got to get off my a$$ and install my gauges! Without knowing the AFR, seems like knowing the ignition timing means nothing

Currently I just gave a tach and scangauage on volt, ign, tps, and cycle through others (load, loop, temps). I have boost/vac and wideband a/f and oil press. still in their boxes

Cruising around at 2500-3500 rpm, the tps is ~25, load is say 50, ign timing is usually ~30. Under boost (load 99 and tps 25+) it quickly drops to half that... is that normal?

I cannot fault you for being slow. I started the thread about gauges for boosted applications at the end of October. It's now mid-March and I just got two of my three gauges working (boost/vac & wideband a/f). Oil pressure should be done next weekend...maybe.

As for the scangauge, I normally set it to trip MPG, instant MPG, RPM, & fWt

Yes that sounds correct.

thanks... this whole project has taken me forever though. I'm a terribly slow weekend mechanic and even slower electrician, plus it's taken me a long time to get a mental grip on the basics of boost--had a lot to learn and still do, but experience is the best teacher I guess

Interesting! now I'm very curious to know what Long and others are getting, and how to interpret it all.
