Video: 408 Duster Accelerate with 02 Sensors (pre-tunning)

Nice to have the dual setup.....It was hard for me to see, especially when accelerating and the camera was jerking around, but I never saw it go much beyond 15. What was the general AFR range under hard acceleration?

For normal light to moderate cruise, like your 60 mph cruise video, I am working to the 15.5 +/- range, I won't worry with up to 16 in these conditions. (340, 10:1 SCR).
