Default Optimum Air/fuel Ratio?

At WOT, what is the optimum air/fuel ratio for making power? I think its in between 12.5 and 13.2 but I don't remember for sure.

Thanks,

Chris

LOL

If you do a search on google for optimum Air Fuel ratio, you'll see 12.5 is the general consensus for max power, and 14.7 (I believe) is optimum for MPG/Economy.

Go dyno and ask to use the wideband.

Or, if you are going to run a power adder, just go ahead and buy your own wideband:

so far, mine is working great
