Elevation And Air/fuel Ratio
If my car is getting tuned on a dyno that is located at 800
feet above sea level and I plan on running at a track that is
located at 300 feet above sea level how much will my A/F ratio
change at WOT ?
Thanks >>>>> INTHERED

Shouldn't change much at all. Day to day barometric and humidity changes can be a bigger variable than what you mentioned. The mass air flow sensor reads and the CPU adjusts.

Yeah, not much change at all. I get more elevation change on my 20 minute drive thru city traffic to work. I can't report times, but my butt dyno only notices differences with 5,000 ft elevation changes.
