Tempted to put this on my list of things to buy for my XF, although I'm worried that it would:
1. void parts of my warranty, or that Chrysler would try to if they found out it was on there.
2. be illegal for stock class autocross racing.
3. at some point fail and leave me either with a throttle stuck wide open or unresponsive. God forbid I would be in stop-and-go traffic.

Feel free to prove me wrong on any of those counts.
