Just got mine, havnt really laid into it yet... just a quick 4th gear burst on a highway from 60-75 or so, it just started really pulling when I let off... I nailed it from a slight roll in first up to about 3500 rpm, but aside from that thats pretty much it. I dont plan on driving it hard all the time, but I will probaly give it some hell occasionaly. How hard do you guys drive yours..? And how hard is to hard for one of these cars? The 4.6 seems like it begs to be revved up.
