Re: What a/f ratio is considered dangerously lean? (MPH)
13.1 is a good bang-for-the-buck ratio that you can run all year (yesterday 80 degrees, last night 30 degrees). 13.5 is doable too, but I like to know I will not have any problems or have to adjust. 14.1 is perfect, but lets face it - who has perfect conditions on the street.
I'm up to 81,000 miles - no fuel related problems. (btw - ignition timing for me is 17.5 degrees)

Most all the cars I have ever had on the dyno made best power between 13.1:1 and 13.3:1.. except for turbo.

when we rolled in, you were 13.5-13.7:1 on the top end.
V-AFC fixed that... fuel pressure didn't do squat.
you left at the same as my car, 13.1:1
