Tune for High Altitude?

Tune for High Altitude?
I just bought a 1996 C2 for my place in Vail. I bought the car from a dealer in Houston, and when I took it for a spin in Colorado, I noticed that it was not as peppy as my 1997 C2 at home in Boston. I had a compression check done before buying the car, and though one of the cylinders is at 85%, all others are in the high 90's, so I don't think it is a compression issue. Is it possible that driving the car at 8,000 feet, after it was tuned at Houston elevation (all of 50 feet above sea level), there is less power? If so, can anyone suggest a Porsche mechanic in the Vail area that could tune the car so that it has its full get-up-and-go? Thanks!

You loose HP as you go up in altitude. No way around this. The car will compensate for the lower air pressure.
What is "tuned" did it get a rolling dyno tune, or an off the shelf chip? There is no "power" adjustment any shop can do on a 96. You can chip it, or do add ons.
Just learn do deal with it & know every one around you is also having the same issue!

Thanks! I probably used the wrong term when I said "tuned". The car is stock. I meant that the car had been serviced in Hiuston, so any adjustments the mechanic made were at sea level. It sounds like HP and altitude are inversely related, and that there isn't a mechanical adjustment on the car to compensate for the change in air pressure. The xar is still a blast to drive. Thanks again!

The bad news is you will lose about 30% of your hp at this altitude compared to sea level. Hence, the appeal of turbid at higher altitudes, as they have the ability to lose less than a na car.

You just lost power due to your height. Come on down, & it will come back to you.
Again, your service has nothing to do with this.
