what is the best setting on my chip is best for in town fuel mileage? 2001 f250 crew cab 4x4. 50, 75,100 or 140? also whats the best setting for cruising on the interstate?
Best setting? You have to play with it and see what fits your driving style. But most likely it will be one of the lower horsepower settings. Mine performs about the best MPG wise in the economy setting although I prefer the tow setting for the shift firmness.
I dont get very good mileage in the DodgeKiller setting at all............
