Yeah, I'm into old thinking, ok whatever. I hate to burst your bubble, but I work on newer cars everyday dude. And my 2.5 pings a little on 87 in the hot weather, so I run minumum 89 for it to not ping. I think the compression is set at the max as it is, for street use. I know I wouldn't want it any higher. But your more than welcome to use you 'new age' thinking and run whatever compression you want in your Duratec. Anyways, I was only offering my opinion. I realize opinions are like a-holes, so you can have yours too.
