with an n/a, I'm assuming you are referring to stillen's upgrade chart (mistake number 1 =) ), intake, ecu and exhaust doesn't help us n/a guys out as much as it helps TT guys. You need just a tad more than that to reduce your time that low. Taking a full second off 0-60 can be difficult, a really good driver could possibly to it with stage 3 and some weigh reduction. I'm comfident that my car could do pretty low 0-60s in it's current state. I don't know what stage to call it, but its like +++++++ stage =D havent tried yet because 18 inch rims aren't helping my times much.
