I guess I'm missing something about the 5 star tune. I drive primarily in very hilly mountainous areas, up to 8,500'. I've been averaging 8 to 8.5 mpg with lows of 7.5. I tow a 2004 CRV. I often use the tow button. I often use cruise in flat areas. I like to go about 62 mph. Strong desert winds are common.
My "5 star" tune is my right foot and engaging/disengaging the tow button. I just don't see where the 5 star tune would be be facial to me. Every once in awhile I will manually downshift but that is rare. I'm seldom in a hurry. For me I just don't see it.
