I know for that every 1000 feet in elevation you climb, you lose 3% of your engines output capacity, and vice versa for descending in elevation, so you gain 3% every 1000 feet. So you should get a good bump in power going down 5000 feet; roughly 12-15% or so gain. But I don't know how they compensate for a tune. I'm almost positive you will have to get it re-tuned when you bring it back to your elevation. Atmospheric pressure @ 7000 feet is 11 PSI and @ 2000 feet it's around 13.5 PSI or so, and that's a good difference.

Just out of curiosity, are you buying the car somewhere in Wyoming?

Any of the tuners here know what the deal is with getting a re-tune?
