It can't really void the warranty as the onus is on the dealer to prove the change you made caused the failure. If you blew any part of your drivetrain using the Livernois tune they might have a case, but if your power windows shit the bed, they couldn't deny that.Hi Andrew, I do not have it but was looking at it as well as it maintains warranty. Do a search on M-9603 in the top right here and you'll see there are some posts about it.
With regards to dealers, certain dealers in Canada are Ford Performance authorized, or so it appears.

I'd prefer Livernois as it offers multiple different tunes, ie: you don't HAVE to run premium gas on certain tunes. However, they're experts on here that can confirm but I believe this voids warranty.

Hey, Andrew, quite a few members are running this tune, including me. There is some debate about which tune is the best and for what reasons, but most of those who have flashed the Ford Performance tune, again, including me, are happy with it. It helps with the sometimes sluggish transmission, makes the whole thing run more smoothly, and noticeably increases power at any speed. Not being an engineer or mechanic, the best way for me to describe it is that, once tuned, Drive Mode becomes what Sport Mode used to be, and Sport Mode takes it to a whole higher level. In fact, after running the tune for about a month, I pretty much just leave it in Drive nowadays. I love this tune, which is not to say that there may not be better ones out there, but to get this much improvement without risking one's Ford warranties is good enough for me!
