I'm all for better performance, and have thought about buying a tuner myself, but is the risk of some random dumbass at the dealer entering that into their system really worth it? We're in the 2009+ forum here, so we all have 3 or more years of warranty remaining on the powertrain. ~30HP gain is a fair bit, and it would be nice to have, especially with a CAI and cat-back exhaust to let it breath and sound better. It seems Ford is pretty much against anything and everything you do to modify the vehicle, and it's up to us to prove it it the mod wasn't the cause of any damage.
I'd bet if I had a tuner, all of the sudden my imaginary transfer case problems would become real, and I'd be paying for the repair.
I'm curious if the weird shifting temperment of the 6-speed has improved after a transmission shift adjustment, or if it becomes even more tempermental. I was just out driving and it tried to downshift or something coasting to a stop light and just slammed itself into gear. Very weird.
