I know (or at least I'm pretty sure) that altitude has an impact on the tuning of a car. What is the impact exactly and how dramatic are the effects? I had my car tuned in Austin, TX with a VAFC and wondering what the altitude of Denver will do - will I be running lean or rich?

 

Since air is thinner at high elevations, thus containing less oxygen, I'd assume you would be running rich. Just a guess though, and to what degree it affects the car I'm not sure.

 

high altitude = less air

SO I would think you would be running rich?

I'm just guessing though...

Echo? haha. (yes I know you both posted at exactly the same time )

 

it will run richer. i ahd my car tuned in sac (sea level) and i live in reno (4800) and it runs richer up here. there is less air up here.
