Stock for stock a gs-t is about even with the svt contour. But add intake and an exhaust to an svt and only gain 6hp, where adding intake exhaust to a gs-t gets you 25hp. Most dsms on the road aren't bone stock unless it's a woman driving it so I'd expect to lose unless you've got some decent mods. I'm not being sexist, but I can't think of any woman over the age of 25 that mods her car.
