Have a gander at my dyno from Saturday. As you can see, my truck's so rich it's off the scale (below 10) until 5000 RPMs (too bad I'm not that rich&#33.

Blown AV Dyno

I logged the runs with HP Tuners' built-in logging tool. Is there anything I can do with Tuners right now, or do I need to get a wideband before attempting anything?

And what wideband is everyone using?
