Help, me out here everything that I read and even on my own system I get an increase on mpg's on the highway but fail to get any increase in the city. My thoughts are by the time I leave home and get to work the system is not even warm up yet or is barley warm. So I can I get the maxium amount of out put of gas to get a increase of mpg
