I have my EFI set up to switch tunes thru my edge cs. I always drive on 5 and haven't turned it down in months. I tried turning it down today to pull a trailer, and had some issues. From 5 if you press down once it goes straight to tune 3. Then it won't change up or down. If you hit the menu button or shut the truck off, it defaults back to 5. Has anyone seen this before?
