Got a 2008 Yukon XL. I bought a Banks Auto Mind tuner and have it deleting my AFM and the economy tune in for the winter months. It seems to be working quite well. I notice my shift points are lower and for all around driving, I like it so far. Mileage gain has been minimal at best. I mainly bought this because I tow a 5000 lb boat in the summer months and was hoping for a little performance gain. Planning on putting the tow tune in before I pick up the boat for the season. Just curious if anyone else has experience with this tuner. I see there are a lot of things you can change but dont really know if I should mess with those.
