high altitude jetting?

does any one know if there was different jetting for high altitude area? my xj was purchased at 7000 feet and I live close to sea level. when I am at the higher elevations it seems to run better!

I know that it makes a difference on carb. motors, but I wasn't sure.

Lower altitude shouldnt make a difference. I know when I raced it was nice tuning at 5000+ feet. When I got to sea level or close i was always a second or so faster.
