I just put in the A/F sensor. I was wondering what the read out should be on a Whippled cobra with about 580HP. When cruising I'm running 14s-16s. If I do a 1/4mile I see like 12s. Does that sound ok?

Don't be alarmed if you see those lean looking numbers at part throttle that's normal!
And guys are gonna say 12:1 is too lean for WOT!

It depends if you're seeing 12.1:1 or 12.9:1. IMO, you want to be in the 11.4-11.8 range to make power and to be safe.
You should idle around 14.7,and i`m running 11.8 at wot.12 is just a tad on the lean side.
i would say 11.3 to 11.6 is perfect. Anything 12 is on the lean side. NO HI SPEED PULLS!!
