Guys, I just bought a cobra and it is coming from Albuquerque, NM altitude 5000ft+ and it is coming to Memphis TN altitude <300ft. The car already has an SCT tune and handheld xcalibrator by shop in NM with a nice A/F layout across the board and ~450 to the wheels.
What shoud I expect to see in the tune after that altitude difference? Will the car run rich or lean? Will numbers go up or down(less of a concern than A/F)?
My thinking, however wrong it may be, is that up there the car sees less oxygen so it needs less fuel and is programmed as such. Down here car will see much more oxygen and may run very lean since fuel maps will be loaded for the high altitude.
Anyone have any input on what I should expect? Thanks
