TURBO BOOST GAUGE
Your vehicle is equipped with a boost gauge that indi-
cates the intake manifold pressure relative to barometric
pressure. The engine management system in your vehicle
intelligently regulates intake manifold pressure based on
environmental (ambient) and engine operating condi-
tions. With the accelerator pedal fully depressed, it is
normal for the maximum intake manifold pressure
(boost) to vary from 11 to 15 psi. If low octane fuel (below the recommended 91 octane
(R+M)/2)) is used, boost will be reduced significantly.
Normal boost levels will return once the recommended
fuel is used and the engine controller adapts to the fuel
octane level.
