Yeah the FICM works great, the mileage is the only downfall. I just want to see if there is something else that we need to check on our trucks that are killing mileage, like on gas motors if the O2 sensor or maf sensor, or spark plugs is bad your mileage drops. Is there something our trucks have that should be looked at.
