PCM Reset and MPG
The previous owner of the truck was mainly highway driving ... now i drive mainly city (about 90%). My question is if I reset the PCM would my MPG get better,worse or stay the same? Am I better to keep the PCM programmed with the previous owners highway driving or reset it to my style of driving. I don't wantto reset it and get worse MPG. What do you think?
