Any one have an idea how much power is lost per 1000 feet of elevation in a turbo diesel? I think its about 1.5%. I know is about 3 to 3.5 % in a non turbo vehicle. I definitely feel a power increase when i'm closer to sea level. Exhaust temps are much higher at high elevation as well because of the thinner air. Any body know the formula? Even at high altitude, gotta love those super diesels.
