        "note": "The compressor pressure ratio = absolute manifold pressure ÷ ambient = (atmospheric + boost gauge) ÷ atmospheric. 10 psi of boost at sea level is a 1.68 ratio. It is the x-axis of every compressor map, and it climbs at altitude where the ambient pressure is lower — so the same gauge boost is a higher ratio (and harder work for the turbo) up a mountain.",
