I joined this forum about two and a half years ago when I was thinking of buying a XF - which I did about two months later. During this time especially I followed a number of threads.

One that did interest me was a fellow installing a V8 in his XF. He went through a lot to tweak the PTCM (with some help) but he got it working and it passed smog.

I do want to add that however cool it is, I wouldn't expect the spoiler to elegantly arise from down to up at 63 mph. But if you run across the code when you're in there...
