im wondering what would be best for my setup since it was tuned at factory in NV at 5000+ ft and i am at sea level, the only problem ive noticed is a hesitation from a stop around 800-1000 rpm but it seems a touch lean at idle and maybe a bit rich to just right at WOT... wish i had the chart for different elevations

In the past 30 years about 90% of Fords are still on the road, the other 10% made it home.
