Air Fuel Ratio?

[ken67]

You can easily run your car at 13.5 everywhere and 12.8 at WOT. This is not "ideal" but it will run well enough tho tune it. You can than try leaner mixtures under light loads and cruze conditions, say 14- 14.5. Dont fall into the 14.7 trap you will pull your hair out . These ratios may be possible and sometimes leaner 15:1 ratios are achievable. Let me know how it goes and good luck
