^ Yes. Straight swap. Not cutting of grill or anything. That's based on the email communication I had with TM tuning. It's Plug & Play. If you are very handy, then it can be a DIY.
You can always double check again by sending another email to them.
btw, I thought you are going to wait for a price drop, like me, to around $250. Last month sale only dropped $50 to $349. This thing which first came out $599.
