Ok,
The car isnt making more power in alititude than at closer to sea level , its that the car will more willingly advance the timing in higher elevations, once you come down in altitude and start pushing the car a bit, the ecu will find that the car is pinging, and reduce the timing till it is no longer present, then slowly advance again till it finds its "happy place" once more. The ecu has HUGE control over the timing, I can modify the base timing map, and where the advance multiplier starts at , but the ecu can still add or pull more timing then it would ever need. ( well, you could if you didnt know what you were doing push the timing map so out of wack that the computer cant come back to a safe point )
There are sensors on your car that will measure atmospheric pressure and help compensate ( most newer cars have this )
And Tyson, that would only work if you trailerd the car to the event , and by the time you were done w 1-2 runs the ecu would be back to normal.
