Does anyone know how to get better fuel mileage out of a 6.7L cummins. Someone told me by taking the DPF off you could get 20-24 mpg
Auto or manual? What year? Cause with a 100k and straight pipe and 18in wheels and 32in tires and a tuner running 175hp or 60hp i still only get 19-20.5 hand calc. and thats running 65 according to GPS and my speedo registering at 66mph thats roughly 1900rpm. Once you hit 70mph in my truck figure on loosing a good 2-3mpg no bullchit. I dont care if people tell me i can get better fuel economy on a higher hp tune i proved that wrong wit my truck and in my business FUEL MILEAGE is key to making a buckIt was Ohio to Florida. We got around 21-22 on the way back, Florida to Ohio. We checked the computer mpg on a few gas fill ups and it was right on.
What technique did you use to determine the 2 mpg increase within the same day???? How many miles and gallons consumed before unplugging and how many miles and gallons consumed after unplugging????Just unpluged my EGR and the same day mileage went up almost 2 mpg more.
