CAT C-13 Poor Fuel Mileage
I have a 2004 525hp CAT C-13 in a 42k lb vehicle that currently gets 5.4mpg no matter how I drive it. I was looking at the JBall Electronics reflash of my ECM to increase the fuel mileage. Has anyone used this company and if so what were your results? They would be downtuning it to around 470 HP which will still get me up the hills and hopefully give me at least a 1mpg increase in fuel mileage.
