Fiesta st at high altitude

[Little bastard]

Have had my fiesta for a year now. My home is at 7000 ft above sea level. The car amazingly does not
seem to be affected. Have driven it as high as 12000 ft. Very minimal
Difference. 15 k on it so far and it has been impressive. This is just FYI for anyone who
might have been curious.
Happy holidays.

I'm at 5400ft and I can tell a big difference in power when I go up the mountain just 1000 feet. When I get to 9000ft the car feels stock and its stage 3

That is interesting. Would be nice to have actual data. Now I can tell quite a difference with air temperature

What did your gas mileage do at stage 3? Highway more so.

I can tell much more with higher air temperature. What did your gas mileage do highway wise at stage 3?

Third time I've posted this. Power difference between 5400ft and sealevel. Same car same tune same temp
