Between 14.5 and 14.9.
14.7 is perfect. But it would depend on the combo.But these are popular numbers for the average car. |

Lower is not a real problem , its high numbers which means leaner , that would be trouble. I think you need wide band sensor to be accurate when going very far beyond the 14.7 number in either direction

I would suggest between 11.0-11.5 AFR.
Some push it to 11.8 I would be scared running it at 12.0 These numbers are for force induction numbers. Been running 11.2-11.5 AFR with a TVS in my Avalanche for 2-3 years now.Works perfect. |

Just don't go into the 10's very much or for very long. It is bad for cylinder lubrication to go too low. Stay above 11.0 and all is happy. Most like 11.5.

What should it be cruising on highway? Say 6 gear maintaining 70 mph about 1750 rpm steady.

If your sensor is behind the cats it will be very steady and in the mid 14's. if it is in front of the cats it will oscillate, and you will see upper 13's to mid 15's. These are part throttle numbers of course. Sensor needs to be in front of cats to be accurate.
