After swapping tuners, updating and getting proper tunes loaded, doing some logs, and 1 custom tune, my feelings have not changed. $400 tuner, $100 custom tune (which was miraculously perfected on the first attempt) and a years' worth of high octane gas, my vehicle doesn't feel any different. I wish I knew more about tuning vehicles so I could better understand this stuff. To further prove to myself I wasn't missing anything, I refueled (from being on "E") with 87 octane. Left custom tune on in place. Drive 30 miles to make sure I purged any high octane through fuel system. No change, no ping, nothing. With respect to potential engine damage, flashed back to stock. Feels the same as it did in February 2014 when I bought the vehicle.
I was really, really, REALLY hoping to tell everyone that I was wrong about this tuner. Unfortunately, that isn't the case. Needless to say, I'm extremely disappointed. Maybe I just have back luck or my vehicle is truly a turd

. Oh well.....
Thanks to all that helped out.
Can my tuner (upon un-marrying to my vehicle), be used on a Ford F150 EcoBoost or Ford F250 Diesel, both are 2014?
