Default Altitude Effects on ECU?

I know my p72 has a barometric pressure sensor, but just wondering how it adjusts the maps, if at all when using uberdata? I figured atmospheric pressure here in colorado is approx 12.2 PSI. Now, say I tune everything here in denver to a nice 12:1 AFR, when I go to sea level would my maps run lean?

It should correct itself.

It should correct itself only if you let it run in closed loop.

I love being here in Golden with OBD0, when i go to sea level i need to take the WB and do tuning on the way :P I hate going to sea level since i get used to the extra power and then come back here and cant stand it.
