High altitude package?
[updated:LAST EDITED ON 24-Dec-02 AT 02:10 PM (EST)]Was it available in later gas trucks? I know the earlier trucks had the option. My truck came from Denver, so I'm kind of curious. But I'm missing my underhood sticker. How would I tell if I did have anything?

The 1991 brochure lists it as an option for the F-150. That's what got me wondering since I figured EFI wouldn't need much different.

The calibration codes were different for trucks originally sold in areas where the altitude was over 4,000ft. They leaned the mixture out even further, to allow for a better base strategy, and some of the later ones even have a different type of O2 sensor.
