So much hostility
Any map that comes pre loaded on the Cobb AP is simply a base map. It will react diferently on every car. Our elevation is high but it is comparable to saltlake city where The Cobb maps are created. I had a custom tune made for my AP by a local named Cory. From what he said Ed is the one who taught him how to tune and he did a pretty bang up job.
I head west quite often so we purposely tuned my car to run a little rich to avoid the posibility of running lean in 0 evelation. Atmospheric pressure in Reno Vs Sac is a pretty big differance.
