Is the needle steady? Does it bounce up and down, or slowly fluctuate? This gauge is a great indicator of both engine health and economy. Check a service manual or on-line reference for details about the readings.
The boost side is a waste of money, unless you have a turbocharger. Not a popular ecomod option...
I've run that gauge for 20 years and it's about the best fuel efficiency meter there is (for ICE).

Thanks for the info. The needle is rock-steady so I am hoping it's a bad source. I'll do some homework and see what's up.
