After recently putting 22"s on my 300c, I noticed that the part of the dash that you can bring up how many miles till you have to fill up is way off now. Before when I would fill up the gas it would say anywhere from 320-340 miles untill next fill up depending on how fast i was driving, now today I filled it up and it said 232 miles. Has anyone else had, or noticed this problem? I really use this feature of the car, and have gone down to 1 mile and its been very accurate. Does anyone know if there is a fix? I have heard of reprogramming the computer, but I have also been told that you dont want the dealership to do this. If anyone has any insight to this please let me know. Thanks
