its been my personal experience that the v8 mustangs , old and new body styles , kant hang with me on the highways . i pull away at will . mostly off the line i have them too but do have traction problems off the line . i end up having to roll off the line and then open it up , even then she'll slide out on me once in a while . i did get my a** waxed one day by a 2008 g6 that had about 10 grand of work under the hood. kant imagine it was the most streetable car but rediculous power , had real nice tail lights too !!
