Altitude Correction Tune?

Altitude Correction Tune? I am at school in altitude of 5000+ ft. My home town, which I go back to occasionally, is ~600 ft. I am going to get a 100 shot tuned soon, what shuold I tune it to air/fuel wise? Everything will be thrown way off. Currently the car is heads/cam and it runs pig rich up here becuase it has a lower elevation tune on it. I'm at a standstill here as I don't know what to do. Is there a way where I can swap tunes from high to low with ease? Without spending ungodly amounts of $$ Let me know

like stroked30th said, your MAP sensor and ALSO your MAF should both note a change in air density and respond accordingly if they are not doing this, i'd say something is wrong and i'd probably lay off the spray until i figured it out.
The MAP sensor is the factory way of changing the tune for altitude. Even if the MAP didn't work, the MAF would notice a difference in airflow VS rpm and the PCM would respond accordingly giiven enough drive cycles.
