Yes ford can find a "footprint" if they look hard enough. Thats for any tuner though. If your worried abouy warranty issues talk to your dealer before you tune (some are mod friendly) or just get the tuner while ya still can and just wait till warranty is up. Oh and congrats on the truck these 6.4s are awesome.

Congrats on making the change, The 6.4 is a mean engine and loves to be pampered! LOL! I would grab a tuner now, and make your decision later down the line when you talk to your dealer!

Enjoy the truck!!
