DA and tuning at a different track?

http://airdensityonline.com/tracks/

you can go here and compare and watch the DA at all the tracks in the USA

sacto is currently density altitude = 255.88 ft BP= 29.98

las vegas is currently density altitude = 2633.25 ft BP is 28.01

I'll def bring my box O jets with me. Should I mess with the timing at all? I'm currently running 37*
