Yup, you were in lean burn. (Unless you were just going downhill!)

Hey Darin! It has 246,000 miles on the OD. More than I would like, but it is expected when it is a 17 year-old commuter car.
I got a super sweet deal!
$1000!
That stretch was
slightly downhill. There isn't much perfectly flat land out in Missouri! Well, towards the west and north, when you get towards the Great Plains. Not where I'm at.
I thought that when in lean burn, you had to apply MORE throttle to provide adequate power. I was feathering the throttle!
On my old Escort, going in to lean burn at say, 50 mph, would be a difference of almost no throttle to maybe 1/3 of full throttle. Load would go from 46% to around 60% having a 17.3 AFR, and the Insight is more than capable of passing 20:1. Is my thought process correct?
Also, the tire pressure was probably spec (38F, 35R) during testing. Definitely getting a boost before I drive it home!
