[QUOTE="cowboy63645, post: 454, member: 112"] The black Bear tune is great! I am running 265/70/17 tires and have no problem turning them at any point in time, and occasionally when hitting second gear when I am on the gas hard enough. I also picked up almost 2 mpg on the highway but I also have 3.42 gears which does help with the longer runs. Also, once you have a tune done, when you send your computer back in any updates for new mods are free. You will have all the customer support and updates for life. [/QUOTE]
