Yes, I did it with my 2012 Focus Titanium. It's easy, simply follow the website's instructions. However, they may need to mail you an updated memory card.
If you have a laptop, take it with you. That way you are not having to run back in the house to upload the version you have to see if you need an update.
I ordered it with a new factory flywheel, exedy slave, and the mmr head cooling mod. Everything should be coming in by Wednesday at the latest and it should be done in about 4 hours. I'm still looking for torque specs though.
