So far I have had the tune in for a couple of weeks. I would guess the car has about 140 HP with that tune. It feels like it has about the same go as my '12 Focus. I don't know for sure but the throttle tip-in seems slower which is good for economy too. I drive mostly county 2-lane roads and I have 120 miles at the 3/4 tank mark. So far I would say it's a great tune for winter or even long trips.
