The stock gauges are fine if you know what they're telling you. Get the engine up to normal operating temps. Use an inferred temp sensor on the engines intake manifold temp sensor. Read the inferred temp. Then you'll know if it's running hot or cold. Take a Sharpie. Put a very small dot on your gauge lens as a reference point. Pull your engine oil pressure sensor. Screw in a pressure gauge. Then mark the oil pressure gauge lens. This way there's no more questing, And no need for more gauges. Bob Dunahugh
