@NM_Life_Defender I like the sound of that and I know what you mean with the trans. Did ford see that you had flashed the ecm? I'm not sure I'd they are able to but I wouldn't be surprised if they can.
Not a peep from the dealership about my tunes. It's been there twice for service since I got it, and they haven't said anything. I obviously can't promise that it wouldn't come up if I had an issue, but my understanding is that they have to be able to prove that the tune caused the problem in order to not honor the warranty. Also told them I was installing the 2FG, and they didn't bat an eye, although that doesn't really do anything mechanically. You could also contact
@GooseTuned and ask for any concerns they have run into with warranty issues. Wilhelm is super responsive, incredibly knowledgable, and will take good care of you.
