I went with the Mountune MR230 kit from my dealer, like it sounds the above person did, as well. It's been a while since I had a new car with a warranty, and I was pretty happy that my dealer worked with me. They are very mod friendly and I feel great having their support. But the dealer closest to my home was not at all mod friendly and seem pretty incompetent, in general. I'm more than happy to drive 30 minutes, for what I've gotten. So I'd say it kind of depends. As for the MP215... it seems like a lot of money for what it is. It's just an intake with a severely limited accessport. What I got could be done better and cheaper using different components, but I paid somewhat for the piece of mind that my dealer will be comfortable with my engine warranty. I also suggest putting on a rear motor mount, at least. i have no idea why Mountune does not include it with their popular mod kits. It seems like a huge oversight. The difference between stock and where my car is now, is night and day. But I can't say what the MP215 would be by itself. But I'd imagine you can feel it. You could spend the money on a Cobb AP3 and an intake and tune for less, with better results. But it would depend on your dealer how much they would stand behind it (you could always return the MAP to stock before bringing it to them). Some people are completely anti-mountune. But I just think they are safe for Ford to feel confident with, if a little expensive. I'm not complaining.
