If your car has one it should be just to the right of the oil pressure/temp gauge. I don't remember which models had them but I know the 85's with digidash didn't have them. They had a tacho/torque meter bar graph thing.

Turbo models with analog instrumentation have a turbo boost guage. Turbo models with digital instrumentation do not have a turbo boost guage; they have an accelerometer instead.

the boost gauge is represented by the height of the tach bars on the digital dash.

Full boost (6.7 psi for 84-87 and 4.5 psi for 88-89) is acheived when the bars are all the way at the top.

If you are planning on running more boost, you buy an aftermarket boost gauge.

still represents intake manifold pressure.

under hard acceleration, you might get up to 0 psi of pressure (relative to atmosphere)

If there is no boost gage on the digital dash turbos, then what is the gage next the oil pressure gage? it looks just like a boost gage with -7 to +7 lbs of boost. Am I wrong here?
