guys or even gals, if you have a Ford V10, get the 5star tune, it will be the best $400 you ever spent on your coach. I cant believe the difference in the shifting, downshifting or lack of. The engine...
nope easy to do. it will come two ways. a pre programed tune that you download, or a custom tune thats emailed to you, you upload into the device via software that you can get on thir website, and then download into your coach.
