Big Al....modding cars is just a hobby....a challenge if you will...nothing more....If I wanted to spend the real bucks to go fast...I would sink the $$$$$ in a ZR-1....but, that is just too easy, and too much $$$$$$. Anyway, that is what this forum is all about for the most part....making all XF perform better...whether maintenance or speed...you can find it out here, once you get by all the BS....
