Re: Taking a trip, Hypertech III ?
During the warmer months and driving to work on rural roads at 62 mph I actually got up to 14 mpg, when it got a little colder here in Illinois, It dropped to 12- 12.5 ? The thing I would like to change is when I'm going 62 with the cruse on and come to a slight incline it will down shift and kick in the supercharge for a few seconds the shift back to 4th.
