seriously assiedude, I run the dog crap out of mine and have pushed her into curves as hard as anyone, powered out hard and she keeps on going, no stall, no hesitation, just raw hp...my only complaint is to me it tends to push going into a right hander at 80-90 mph...I just don't trust it that much, but as soon as I transition, I am back on it all the way to the floor for the next turn...I have done evoc in my earlier yrs on the police dept, and get to play at the academy from time to time...we push our patrol cars this hard, so the XF is a breeze on the obstacle course compared to a Chevy Impala, or Crown Vic, haven't gotten to try a Charger yet...just try the things mentioned here and we will get you kickin' butt in no time....
