readings? I found charts telling me how to use readings but they say,
not applicable with turbo. My question is what are normal readings for

vacuum readings are relly more of a reference than a specific value. It depends on the cam and valve timing compression and other things as to what you will really see. Basically anything that effects the pumping efficiency will also have an effect on the vacuum readings.
Generally you can expect to see just at or below 20" at idle, and a bit above that during decel. If everything is running normally I'd say to note the readings and use that as a reference to indicate if something is going wrong.
