Altitude and F/I? I was curious does altitude still affect boosted cars?
6# is 6#... simple as that correct?
So if this is true a turbo'd car running 12.5 at 5000ft above sea level will run the same time as a car at sea level with the exact same setup...
This correct or no?
Just a little thing I have been wondering.

Not quite. Your still making 6 lbs over the current pressure, but it still less then at sea level. For instance, my truck makes 7psi of boost. At sea level that's about 156kPa. That same 7 psi at 4800 ft where I live in WY, is only 135kPa. I have to make about 2 more psi of boost (9psi) at 4800ft to get back to the 156 kPa.
