Is it hooked up correctly?

What do you want to tune with it, just fine tune the AFR's?

On an n/a I believe to start I'd lean it out SLIGHTLY in the top end, like 5%..

To do it properly you really need an EGT, wideband or learn how to read plugs (and be willing to pull/clean them every 1/4 mile to see your results)

If you search there was a guy on here raving about his gains with an SAFC a long time ago, I think he leaned out the top end alot.. But I don't remember, search for the info and you might find it. This was back in 2004/2005 probably.

you'd definitely want to use a wideband o2 to tune it, most dyno's have them
