For regular driving you can stay in the low 15s for ratio- up above 50% throttle and in the upper revs is where you need to start looking at getting your fueling into the rich area.

Part throttle is fine in the 15s- no big deal at all.

Slowly ramp your a/f ratio numbers down from stoichiometric through to mid 12s at full throttle. Make it a smooth transition. After you're done tuning without nitrous, turn on the juice and make sure you're able to run just below 12:1.
 
ok, to tune with an safc do you need a wideband, I understand it's going to be a more acurate tune, but do you need a wideband. it is mandatory.

one more question, could you say... borrow someones wideband, tune with it then uninstall it?

For a good tune, yes, a wideband is mandatory, regardless of whether you have a SAFC or standalone.

And yes you can borrow someone's wide band, tune, then uninstall. I'd just go to the dyno though. I assume dyno's hookup a wideband when you pay for the dyno time. I have a wideband though, so I have the tools to effectively tune it without the dyno. But dyno is THE best way to tune.

I live in San Luis Obispo. I am almost done with my build. 11.5:1 compression, pnp'd LS head, obd0. I'm going to be tuning with a socketed pm6 w/datalogging port, and an Innovate LM-1 WB, RTP with ostrich, tuning with Turboedit. I am just waiting for my pm6 to come back to me, it was throwing a solid CEL when I plugged it in, so I sent it back to be replaced. I'll let you know how my tuning goes. If it goes well, I might consider doing it for some others.

Only if you show me a good time... :p
But seriously, if I get my car together soon, I'll consider it. Got the whole rest of summer.
