I've been searching, but haven't seen much talk about programmers on the 2014's....is this cause of warranty issues or what? I saw a few guys mention getting custom tunes, but I was actually just going to get the Hypertech speedometer calibrator for new larger tires, but for another $100 its almost a no brainer to get a programmer even though I'm not really looking to go changing anything crazy. Anybody out there have experience with any of these?
