gauge values

as pointed out, the 'gauges' are not in reality gauges. Basically idiot lights but not much more so values (numbers) are really meaningless in most vehicle. These gauges read info from the ecm/ecu and if you were to hook up a scan gauge you would see that they are not real world. Normal may be anywhere from 10-50 psi of something, water temp is what ever they want it to be, but anything over 220 deg is normally where it stops being 'normal'.

the numbers really mean little anymore IMO. You want real numbers then you need to hookup direct reading gauges.
