Mid range seems to be aggressive in DS, but nothing different in D for me anyways. I reset my economy gauge just before I installed JB4 last year, and between JB4 and Dinan, I still get 27.4 MPG average. I drive my car HARD! I have noticed with Dinan, I get better mileage than with JB4. I also notice that with eco pro on, throttle response is zero. You really have to press the pedal to get the car to start moving down the highway. That might also be due to the downpipe getting rid of the hot gasses too quickly for the low throttle angle.
