Just get a vehicle and worry about it running at all, not about making alterations for "altitude." motorcycles and other small carbed engines seem to like to be re-jetted at about 6000' though, again well above the playas elevation.
If you bought at altitude, any factory changes should have already been made.
I saw the pathetic condition of underpowered cars in Denver.
Great place to work on cars.
I even saw one brought in and left as too sad to fix.
It ran like a cartoon car.
My modified car ran up and down the hills like it was on flat land, as it was built for.
It still lost 50 to 100 horsepower due to altitude.
Why not use every advantage?
