If you dynoed at sea level and used the SAE 1359 Rev 90's base baro pressure of 29.235, with a 1.00 correction factor and then dynoed at 6000 feet, the absolute baro pr would become 23.259 and the HP/TQ correction factor would be 1.286 with no other changes in temp or humidity. So if I did my math right, you would lose 22.24% HP and TQ.
