ok all I am going to test the speed verses mpg quandry this weekend and will post the results. my last trip of 200+ miles one way yielded unexpected results. at 1950-2000 rpm mileage was mid 20s . I increased the speed to make my grandsons soccer game to 68-70mph and I had a mileage jump a big jump 6-8mpg at 2400rpm. I suspect the turbo sweet spot. I am going to try it again and will keep all informed
