7200' ft elevation no good for S2000 performance.
I work at 7200' ft elevation in flagstaff, AZ. I drive my S back and forth often from where I live which is at 1200' ft elevation. I get so diapointed when i reach altitude, the performance goes to crap.
Any ideas on what to do to help this.

I'm not surprised by this in the least....
As a rule, the higher the altitude the less performance the car will exhibit because there simply is not as much oxygen in the air for the engine to combust.
That said, a turbo application will be less susceptible to altitude because all stock turbo cars that are equipped with wastegates of some kind(internal or external) have some excess boost capability built into them. As the altitude goes up, the turbo will build boost to maintain O2 levels(as detected by the O2 sensor built into the MAF sensor/MAP sensor that are similar to normal sea level operating levels. This works up to the point where the wastegate is closed all the time and the turbocharger's capacity for extra boost is reached, at which point power levels begin to drop proportionally to altitude increase, just like a naturally aspirated car's powerplant.
An engine as high strung as the F20C, which already had optimised flow characteristics, will be extremely affected by the altitude variations that you're talking about, and the fix for your problem is to turbocharge it, or bring a bottle with you(NOS). Good luck!
