DA and tuning at a different track?

so im running my 65 dart at mats the year and I have a couple questions when it comes to tuning. currently the car runs consistant 12.0s @ 110-113 depending on temp. my track is at sea level and this time of year is perfect for drag racing. ive been tracking the DA in vegas and it always seems to be at about 2000ft this time of year. the race isnt until the end of march so it will be warmer.

what kind of changes should i make to help with the tune up for the higher DA and elevation?
