I was surprised how much more power this has given my 2002 dodge cummins. I have it set on the #2 setting and it has definitely made a difference. MPG has also gone from average of 18 up to 22. This is mostly mountain driving and pulling trailers. An easy, fairly cheap upgrade. I kwould highly recommend it!!
