AFRs

I did see 10s & 11s in your video, corresponding to "Tip in". AFRs under full power should be in the high 12s or low-mid 13s, other than the 2-3 seconds where the accelerator jets are spraying. Constant speed on level road about 14-14.5, and on "tip in" (accelerator jets spraying) drop to low 12s then leaner again as above.
Idle no load 14-5 -15 AFRs

Per Jim Steck there is measurabe power loss richer than in the mid 12s
