K I T T

Just swapped a jdm eg9 cluster on my hatch and I noticed my fuel gauge moved very slow. When I had 360 Kms since I filled up the tank, the gauge was still on the 1/2 point. I thought great I improved the milage with a cluster swap but then just today I got to work, my usual 20Km drive and as I reached my destination, my fuel gauge plunged to a little bit below 1/4 mark.

Any one noticed this on your cluster swap?
