I understand this isn't a "1/4 mile car", but neither was my 951. And I had to see what it ran!
I'm really curious to see some 1/4 mile times before and after the Xede. Reason being that there are some areas running .4-.6 faster than others. So if I ran a 13.5 here it would probably be a 13.0 in, say, Michigan. I ran into this when I used to drag my Lightning. We'd hit 13.2's with a chip/pulley in Arizona and the East Coast guys were running 12.7's with the exact same mods!
So let's see 'em! Post your 1/4 time with/without the Xede!
